Motion sensor radius. How to choose a street motion sensor to turn on the lights: tips and reviews about manufacturers. Disadvantages of microwave DD

A motion sensor is a fairly miniature electro-optical device that detects the movement of objects in the area where the sensor is triggered. The device by itself is quite useless, but when combined with a sound or light alarm, lighting devices, a video recorder, a hood, sound equipment and data transmission equipment, it is simply irreplaceable.
The task of the motion sensor is to detect the movement of an object in its coverage area and provide supply voltage with a selected delay to the devices connected to it. As a result, the lamp, siren or any other device connected through the device turns on.

Scope of application

Automatic lighting control: in Everyday life, most often used today are the most simple sensors movements to control the illumination of a certain living space or territory. They are recommended to be used to control lighting in garages, basements, entrances of houses, local areas, and street lamps.

It is recommended to use where a person’s hands are often busy or it is inconvenient to look for a switch, as well as in all places where round-the-clock lighting is not required. This is where automation comes to the rescue. Simple automatic sensor, makes the decision to turn on/off the lighting device connected to it in right time and in the right place.

Security alarm: the use of the device is also justified as an element burglar alarm. A correctly configured and installed sensor will detect a security line violator at a distance of approximately 12 meters, and then the warning system (siren, lighting), and possibly photo and video recording devices for the violation, will be activated. This is especially useful when protecting garages, country houses, parking lots, warehouse doors, etc.

Modern security systems, for example, based on microcontrollers such as ARDUINO, can even send you an SMS message about the fact that the device has been activated at a protected facility. This will significantly increase the chances of property safety and scare away potential intruders. So, a watchman will come to the sound and check the object, and an SMS message in the form of a call to mobile phone will be an additional guarantee of this.

Various automated systems control system (ACS): various motion sensors are also used in production. Such devices operate on conveyors, elevators, scales and their task is to provide technological process production, and in case emergency situations turn off the equipment.

Classification of devices

According to the installation method, devices are divided into:

Invoices; ceiling or wall mounting option using conventional dowels. Usually mounted at a height of 2.5-3 meters from the floor level. They may have an internal/external corner bracket for mounting on a corner. As an example, this is a motion sensor from DELUX (China) YCA1021, it has a viewing angle of 180°, a detection distance of 11 m, an operating temperature from -20 to +40 degrees Celsius and can switch a load of up to 1.2 kW.

Built-in; are mounted in a wall or ceiling, and are located in the same plane with it. For example, Uniel USN-015, a ceiling-mounted, built-in device, with a maximum viewing angle of 360 degrees. Usually installed in mounting boxes (the same as for sockets) next to a switch, lamp, or in a hole in the ceiling.

There are also hybrid options, for example, a kit from COCO (the Netherlands) for a corridor, hallway, bathroom - will automatically turn on the lighting when entering the room. The company offers to purchase a wireless motion sensor AWST-6000 and a built-in radio switch ACM-1000. The devices have the following characteristics: receiver operating range 70 m, powered from a 220V/50Hz network, transmitter powered by two batteries (AA size) 1.5V. The kit has a protection class of IP20, and a switching power of up to 1 kW.

By climatic version devices are divided into:

• For outdoor use; Such a motion sensor for turning on the light “sees the object” at a distance of up to 500 meters. The operating range of the device is from -40 to +60 degrees Celsius. Dust and waterproof housing design.
• For indoor use; Such devices are intended for indoor use only. Operating range from -20 to +40 degrees Celsius.

By type of power supply used:

1. From the lighting network 220V;
2. From a battery or batteries;

Varieties by wave spectrum

The infrared view reacts to the thermal radiation of an object. It is clear that warm air currents from heating radiators and air conditioners, as well as from animals, can cause false alarms. Make settings and installations with this in mind. Such sensors are used only indoors. This type is absolutely harmless to health.

The ultrasonic sensor emits waves in the frequency range from 20 to 60 kHz. The sound is reflected from the object, captured and analyzed by the sensor. The range of such devices is not high, and when moving slowly, the device may sometimes fail to operate. Ultrasound can be a good way to repel mosquitoes, but if there are dogs and cats in the house, you should not install such a sensor.

Microwave: instead of a sound wave, an electromagnetic wave is used, with a frequency of approximately 1 GHz. The device is small in size and can be hidden during installation. The range of this type of sensor can be quite large and is determined by the power of the microwave transmitter and, of course, the sensitivity of the receiver. The environment does not particularly affect the operation of the sensor. The price is the biggest drawback of this device.

By number of contacts for installation:

• Two-pin sensors are used in conjunction with conventional lamps. We consider as ordinary any lamps that are included in the 220V lighting network, like a simple and well-known incandescent lamp.
• Three-pin models can be used with any types of lamps. They are also recommended for connecting the coil magnetic starter, when connecting a powerful load.

Criteria for choosing the best model

When choosing a sensor model, you need to clearly understand in what conditions the device will be operated and what load it will control. Therefore, when choosing, consider the power of the lamp that will be connected to the sensor. Please note that there are already models of lamps and even lamp sockets on the market that already have a built-in motion sensor

Floodlight model with LED-FL-10 sensor

For example, a model from the company EUROELECTRIC with the trade name LED-FL-10. This is a LED lamp measuring 100*125 (mm), with a power of only about 10 W, providing a luminous flux of 800 lm. The most important physical characteristics this is the viewing angle and range.

The viewing angle of the sensor, this value in degrees, determines the “viewing angle” from the point where the sensor is located. A street spotlight requires a sensor with a viewing angle of 180-360 degrees, but to control the intercom door lighting lamp in the entrance, this is quite enough ceiling option sensor with a viewing angle of 20 degrees and above.

Radius of action. For household use A distance of 10-15 meters is quite sufficient; this is the detection range that most models with an infrared sensor will provide.
Various connection schemes and choice of mounting location. Correct placement and configuration of any device is the key to it proper operation for a long time.

During installation, it is necessary to ensure a detection zone for moving objects, protection from external influences that could cause incorrect operation or failure, as well as a reliable connection to the electrical wiring. The installation height of the device is regulated by the manufacturer. Technically, the work of installing the sensor is not complicated, but it is specific and requires some practical experience.

Therefore, if you do not use in life indicator screwdriver, tester and rubber gloves - it is better to immediately contact specialists. 2-pin sensors are the easiest to install; they are connected in series with chandeliers, lamps or single incandescent lamps. In cases where it is necessary to turn on the light forcibly and for a long time, we recommend immediately installing a switch parallel to the sensor (this option is possible when working in a garage inspection pit).

In long or large rooms(corridors), it is advisable to install several sensors at once. They are connected in parallel, and the activation of any of the sensors closes the circuit and turns on the lighting in the entire corridor.

Setting the sensitivity of the device

LUX – this parameter determines the illumination at which the lighting lamps will turn on or off. When installing, it is advisable to first set it to the maximum value.

TIME – determines the delay time for turning off the lighting after a person has left the operating area of ​​the device. Usually this value is more than 10 seconds. Consider the length of the room's corridor and the time it takes to close the door with keys.

SENS – determines the device’s response threshold, i.e. sensor sensitivity. The greater the sensitivity, the greater the motion detection range. Selected individually.
MIC (microphone) – usually also selected individually, but initially we recommend setting it to minimum.

Today, street lighting is of interest mainly to residents of the private sector or holiday villages. For apartment buildings Street lighting is handled by city services.

But for summer residents and people living in private houses, great solution There will be an installation of a street motion sensor to automatically turn on the lights in the garden plot.

Such a street device is practically irreplaceable; it immediately solves several problems, not only regarding street lighting, but also the possibility of protecting private property.

Range of choice

Today there is a tendency towards an increasing penetration of all kinds of technical innovations into our daily lives. Thus, sensors that respond to motion are increasingly appearing in our homes and on the streets. Using such devices, you can automate the process of lighting any room or street.

The sensor's response to various types of movements is widely used on the streets of cities and villages. This allows you to make movement on streets and roads safer and more comfortable.

This sensor is a small plastic device, which can be installed outdoors almost anywhere.

Note! The choice of location should be made based on the requirements of the device. The motion sensor must have a wide range of operation in order to adequately and fully perform its functions of switching on Sveta.

Instrument placement

All street sensors, responding to various types of movements, belong to external devices. They can only be installed outdoors. Therefore, unlike internal devices, can withstand low temperatures.

Outdoor equipment of this kind, unlike indoor sensors, has an increased angular coverage of 180 degrees.

A sensor for turning on street lights, just like internal devices, can be of the following types:

Microwave, Ultrasonic,
Infrared

• microwave. The device captures a signal in a certain range like a locator;

• ultrasonic. Its operating principle is to detect changes in the reflection of ultrasound from objects. In terms of its organization, it is recognized as the most accessible and simple;

• infrared. It works on the principle of a sensitive thermometer and responds to changes in temperature in the serviced area. It can be adjusted to human body temperature, which will avoid possible activation of the device when passing near a pet.

On the market electronic devices You can find infrared motion sensors to turn on two types of lights on the street:

• active. Such a sensor is very often used for lighting and protecting the perimeter of a house, as well as a fence;
• passive. This type of device is better suited for protecting wide areas. They are placed in front of the front door or at the gate.

It is also necessary to know that sensors for turning on lights on the street when there is movement in the area of ​​their operation may vary depending on the installation location:

• ceiling;
• wall

As you can see, the range of choice is quite large. Therefore, when purchasing a device, you should think through all the details of its further use and placement in order to buy what you need.

Selection options

To make the right choice, the entire available range should be assessed according to the following indicators:

• location;
• fastening method;
• degree of security;
• power and range of equipment;
• dimensions and dimensions;
• the boundaries within which the signal should be triggered;

Note! It is important to remember that the motion sensor can only monitor the area it can see. At the same time, any light structures, of which there are plenty on the street, can reduce the viewing radius: a cornice, a fence element, hanging lamp etc.

• the ability to fine-tune the operating parameters of the device. Interestingly, some sensors can even be triggered by human breathing.

In addition, the choice should be made based on the following parameters:

Device placement

• high quality lighting. There should be just enough light to illuminate the required area;
• speed of turning on the lighting in the presence of movement;
• aesthetic lighting and appearance device;
• durability.

Having assessed the available offer on the market or a specialized store according to the above parameters, your choice will be the most optimal and will fully satisfy all your needs.

It is important to note that the sensor must be able to connect not only to the lighting device, but also to other equipment, for example, to sound equipment. This is especially important for the street, since as a result you will not only get the lights automatically turned on at night, but also an alarm.

Where are they used?

The main purpose of a motion sensor, as you might guess, is to turn on the lights on the street at night. This function is very popular in the following situations:

• in holiday villages where there are problems with street lighting by local authorities;
• lighting personal plot at night, without the need for mechanical connection of lighting;
• lighting in hard-to-reach places remote from the main building;
• as a device that informs about the entry of strangers into the territory. In this case, the sensor turns on the light and activates the sound signal;
• lighting of storage rooms, garages and other outbuildings.

In addition, automating the switching on of lighting when there is movement in a given area allows you to save energy. And this is very important, because in Lately the electricity bill is increasing.

How the device works

As noted above, the principle of operation of the motion sensor is that the device reads a certain signal, depending on the model, and closes the electrical circuit, which leads to the light turning on.

Principle of operation

The operating algorithm of the device consists of the following stages:

• the device reads signals coming from the controlled area;
• when changes (movement) are detected, the signal enters the capturing matrix, and the device closes the electrical circuit;

Note! A special capturing matrix - a Fresnel lens (photocell) - can act as a signal receiving sensor.

• closing the circuit turns on the light.

Any street sensor to register movement and turn on lighting, it works on the principle of continuous control over the selected viewing area.

All street motion sensors operate on this principle. Moreover, each device can be configured individually, which eliminates the possibility of it being activated by pets. But in this case, you should remember that the light can be turned on by vehicles passing by or just a passerby.

Separately, it is worth noting that during its operation, the street sensor also checks the level of illumination of the controlled space. So, if movement was detected during daylight hours, the light will not turn on.

Having an assessment of the controlled area for illumination allows you to save energy and receive automatic lighting only when needed - at night. Wherein false positives sensor can be minimized as much as possible with proper tuning.

Settings

Motion sensors are adjusted using special potentiometers, which come in three types:

• time. That is, this is the time interval during which the device will operate. Typically this parameter is set in the range of 5-10 s. Correctly selected delay time will avoid unnecessary activation of equipment. The time interval depends on the model purchased;
• sensitivity. The speed of the equipment’s reaction to movement in the control zone depends on how much higher this parameter is. In a situation where frequent idle triggering occurs, the sensitivity of the sensor should be reduced. In order to determine the desired sensitivity of the equipment, an average of three adjustments are necessary;

Note! Sensitivity adjustments are made depending on the time of year.

• illumination level. You select the level of illumination to which the device will respond by turning on.

Having made the correct settings, the sensor will operate without failure, just like a watch.

Installation of the device

Street sensor connects to the electrical network in the same way as a conventional switch. It is better to have professionals handle the connection, but you can do it yourself if you understand electricity.

The connection procedure is as follows:

• turn off the electricity;
• open the device by removing the protective cover;
• connect according to the required diagram;

Connection diagram

• We connect the cable from the sensor to the general wiring of the house. Connection occurs via junction box;
• After that, we install sensors that respond to light levels. In everyday life they are called twilight switches. After connecting and setting them up, the device will only operate at night.

As you can see, the choice of street sensors that respond to movement by turning on the lights is quite extensive and requires scrupulousness. But then you will be able to fully appreciate its advantages and comfort from automated connection Sveta. But do not forget that the key to success here is not only the right choice, but also proper installation.

Homemade switching power supplies with regulators Overview and connection of the electrical panel for external lighting devices

Today, the issues of using energy-saving technologies for one’s own needs are becoming increasingly relevant. To significantly reduce energy costs, people use special devices, called motion sensors for lighting. How to make the right choice? And what is the purpose and operating principle of these products? Let's look at this in more detail.

For those who want to use resources efficiently, motion sensors are practically necessary attributes everyday life, because their use saves about 50-80% of consumed electricity.

Motion sensors are appropriate everywhere, in corridors, in storerooms, and on stairs - wherever people are for a short time, or, for example, if your hands are busy. When an object enters the coverage area, the light turns on automatic mode, if there is no movement for a specified time, the light turns off. It is also additionally possible to set a short signal mode, which is used to turn on an acoustic device that controls the door (doorbell, bell). Such a simple solution will save energy, increase comfort and ensure the safety of your home.

Motion sensor for street lighting

Since the benefits are obvious, many people are eager to purchase motion sensors for lighting, but they just don’t know what parameters to use when choosing. Here's something to think about:

• where exactly the device will be used - it could be a street, an open shed, closed room: choice by mounting method, degree of protection, built-in or mounted;
• power of switched equipment. This parameter implies the image of the sensor installation - for one lamp daylight, for thermos, refrigeration room. There are models with different power - 200V and higher, depending on these indicators the installation conditions change, dimensions;
• configuration of the trigger zone - at this stage it is important to take into account the fact that the motion sensor only controls (the main emphasis!) visible area. The radius of action is reduced even by light structures, for example, cornices, sconces, pendant lamps;

Important: you need to remember - glass is an obstacle to the passage of infrared rays, and accordingly, the controlled area is reduced.

• possibility of precise adjustment of the on/off response time. This function most relevant for large premises, where several sensors are installed over a large area, but they do not completely cover it. It turns out that in such conditions a person’s actions are very important - he must have time to reach the next sensor or have time to complete certain work after returning to the coverage area;
• sensor perception angle – products are produced with a viewing angle of 180-360 degrees. For example, sensors with a sensing angle of 180 degrees are in most cases intended for input-output response and are mounted on a wall. If installation is carried out on the ceiling, this means that the device has full angle review;
• the formula for the ratio of active and passive zones is a parameter relevant for offices and recreation rooms. Registration of people present is faster if the zone rotation is higher.

Important: some models are adjusted to human breathing.

Operating principle, functionality

Motion sensors for lighting are a popular, convenient product that solves various problems. This device operates using infrared radiation: a programmed signal reaches the captured matrix.

Often sensors work in conjunction with electrical appliances, and they can also be the main ones in the alarm system and video surveillance. That is, motion sensors are used to harmlessly turn on the light in the passage area, to ensure the safety of housing.

Motion sensor for lighting - convenient and functional

The sensor automatically detects the presence of movement, closes the circuit and turns on the light. The basic principle of operation is continuous monitoring in the observation area: when a moving object appears, the thermal field changes, it is higher than the ambient temperature.

Using a special lens called a Frankel lens, a signal is sent to the photocell, which causes the circuit to close. In the control zone, the sensor is triggered even by minor movements, for example, if a sitting person sways.

Important: motion sensors are configured in a unique way - they do not react to pets, but they sense objects perfectly large sizes: car, person.

Purchasing such a device will not put a big dent in the budget, and its use will bring tangible convenience: a person enters a room, the sensor turns on the light, exits and the light turns off automatically (after a specified time). At the same time, there is no need to look for the switch and remember if I forgot to turn off the light, for example, in the pantry.

Possibility and customization tools

Motion sensors are configured using potentiometers, there are three of them:

• time interval—specify the period during which the sensor will operate. The values ​​are set in intervals from 5 seconds to 10 minutes (depending on the model). This is the simplest of all settings - you need to estimate how often a person appears in the detection zone and set the delay time for turning off the lighting a little more than this value (1-2 minutes). This is done to avoid constant on/off switching;

• sensitivity - the higher it is, the better the device responds to movements. If there are a lot of triggers, it is advisable to reduce the sensitivity; the same applies to spontaneous activations. Basically, this parameter is configured in 3 times. It is also necessary to reconfigure the sensitivity depending on the time of year, for example, in the summer the sensor works normally, but in winter it malfunctions. This is explained by a reaction to warm air rising from the heating device;

• illumination level – for proper operation of the device during daylight hours. When motion occurs, the sensor determines the level of illumination; if it is below the threshold, the device operates; if it is higher, it does not operate. Yes, this is quite logical, why turn on electric lighting in the room during the day?

Advantages of motion sensors

• compactness - installed unnoticed, absolutely without damage to the interior;
• the savings are obvious, because the light turns on only when necessary;
• convenience for owners of private houses - sensors are installed on the porch, on stairs, in basements and storage rooms: moving around the house becomes very practical;
• a kind of alarm against thieves - if intruders break into the home, the light turns on, announcing that strangers are in the house.

Classification, scope of use

In fact, motion sensors were originally intended to work in a security alarm system: they transmitted an alarm signal to the control panel. Manufacturers have gone further by developing models that include floodlights, street lighting, sirens, and power equipment.

The use of motion sensors in the yard will ensure safe movement at night

Motion sensors are divided into ceiling and wall. The principle of their operation is the same, they are simply selected individually, depending on the installation location. Also at the present time in landscape design street lighting poles with sensors play a significant role.

People understand that they need to strive for savings Money Therefore, motion sensors are widely used for street lighting. They must meet the requirements and perform a number of functions:

• security lighting of areas (cottage, garden);
• aesthetic lighting of houses, parks;
• lighting the movement of people walking along the street.

Motion sensors that are installed on supports differ from home models - they are characterized by a large coverage angle. Range – 12 meters.

Street lighting is economical and practical solution: the sensor transmits a signal to the lighting system only when a person approaches

Infrared motion sensors are either active or passive. The first option is used to protect the perimeter of a house and fences, and the second is used in alarm systems to protect wide sectors, for example, approaching a door, guarding a gate.

Installation of motion sensors

The technical side of installing motion sensors is not too complicated. But if you don’t have confidence in your abilities, it’s better to entrust this process to a professional. The cable of this device is connected to the general wiring of the house through a junction box. Plus, sensors are additionally installed that react to changes in light intensity; they are also called twilight switches. This is necessary so that the sensor functions only in the dark.

There are a huge variety of motion sensors, each of them performs a specific task: to illuminate the pool, to start the fountain pump. When installing the sensor, you should take into account the size of the room, the location of windows and doors, since these indicators affect the correct operation of the device.

Important: the motion sensor circuit for lighting is similar to the operating principle regular switch. In both cases it closes or opens electrical circuit, into which the lamp is connected in series.

If it is necessary that, despite the lack of movement in the room, the lamp constantly works, a switch is added to the circuit, which is connected in parallel with the motion sensor. In this case, the switch duplicates the operation of the sensor, which means that the light can be operated forcibly.

Connecting motion sensors

It is also possible that, due to the characteristics of the room, one sensor does not cover the entire area, then a connection diagram for two motion sensors and a lamp is used. When one sensor is triggered, the circuit is closed and voltage is applied to the contacts.

The rated power of the motion sensors under consideration is 500-700 W, this limits their use for heavy loads.

Important: in some cases you need to connect several powerful electric lamps at once (yard lighting), then it is best to use a magnetic starter.

Motion sensors for lighting today find extremely wide application. These can be hotels, office and administrative buildings, educational institutions, Sport halls, parking lots, retail establishments.

The feasibility of using motion sensors is confirmed by arguments of energy saving, as well as convenience and practicality. Their payback periods depend on the total power of the connected lamps. But one thing is for sure, for low quality sensors that break immediately after installation, they will constantly be pushed aside. That is, it is better to overpay and get an excellent device than to buy a low-quality product.

Devices with the ability to detect moving objects are now widely used to ensure their own safety. Motion sensors for turning on lights activate home lighting for trouble-free movement through a dark area of ​​the house, notify about the presence of strangers, and transmit a signal to the remote control of a security organization in the absence of the owners.

In a word, it is a necessary and useful thing. About the types, advantages of this or that type of device, self-installation– described below.

Read in the article:

The essence of the design is the principle of operation of motion sensors, types, advantages and disadvantages

The sensor works by recording movement with built-in sensors. They, in turn, are connected to a device that has a light or sound function - a lamp, flashlight or other equipment. Once in the “field of view” of the sensitive elements, a moving object risks being detected in the first seconds, which is notified to the owners by a connected alarm.

Important! The detection function is limited by range or viewing angle. Therefore, it is important to correctly install the street light sensor to turn on the light in such a way as to cover as large an area as possible.

The types of sensors are varied:

1. By location – external, internal.
2. By type - ultrasonic, UHF-based, infrared and combined.

External

External motion sensors to turn on the lights will help prevent entry into the area. They cover and control most local area, so, as a rule, several of them are purchased to monitor the area around the perimeter. Response radius – up to 500 m.

Domestic

They are weak to external weather manifestations. Strong wind, rain, hail and other precipitation can damage devices or reduce their efficiency. Inside, in a calm environment, moderate humidity, the sensors are active and effective. Designed primarily for turning on light in a dark room, lighting stairs, locks and other places without activating the main electricity.

Ultrasonic

These outdoor motion sensors for perimeter security are based on the principle of reflecting waves that are not perceptible to the human ear from surrounding objects. Naturally, the frequency of impulses of the living differs from others. It is the changes that are recorded by sensors. The disadvantages of the device are the following: they irritate pets, there is a reaction only to fast-moving objects, recording of “guests” of flora and fauna - this causes irritation, especially at night, small area coverage. But at the same time, the sensors are a budget option that is resistant to external manifestations.

Infrared

Sensitive motion sensors to turn on the lights. The temperature of the human body is high compared to the rest environment. The difference is captured by a touch sensor with lenses and mirrors, then sending a signal to a light or sound device. The quality of the device is determined by the number of photosensitive lenses - the more there are, the better the “catching” ability. The advantage of the sensors is safety for households and pets, good accuracy and detection range. However, in this case, the device can “confuse” the heat of the human body and a boiling kettle, for example. Many owners note poor adjustment and unresponsiveness of objects whose coating does not transmit IR rays.

Microwave sensors

The action is based on the principle of operation of a motion sensor using the radar method - sent signals are received back. If the frequency changes, then chain reaction, including a sound or light device. Pros: high sensitivity, even through obstacles - a wall or glass. Minuses: high price, triggered by the slightest provocation, adverse effects on the human or animal body. Such devices are used primarily for monitoring business or warehouse areas.

Combined instruments

As a rule, they combine infrared radiation and UHF. Among the advantages are maximum sensitivity and wide coverage area. There are practically no downsides except for one drawback – high cost.

Review of manufacturers and prices

To correctly select a motion sensor, you need to know two parameters - operating conditions ( external view or internal) and controlled load (power lighting device). For the convenience of consumers, we offer separate sensors or lamps with built-in sensors. Let's look at some models:

Model	Photo	Characteristic
LED-FL-10	Combined device for external viewing at 120⁰	Product from the Euroelectric company (EUROELECTRIC). Compact dimensions LED lamp– 100*125 mm – with built-in sensors, allow you to install the device in an inconspicuous place, invisible to the eye of intruders, without spoiling the overall concept of the interior. Power luminous flux at 800 lm - only 0.1 kW. The viewing angle of the models from the manufacturer allows you to purchase both a motion sensor to turn on the lights on the street with a requirement of 180–360⁰, and a simple ceiling structure For front door with a parameter of 20⁰. The average price is 940 rubles.
Feron/LX19B	Indistinguishable from a household switch	The increased power of 0.6 kW allows the sensor to operate at a distance of 9 m and with a 120⁰ field of view. Such a device, with its low cost of 250 rubles, is suitable for country houses with seasonal residence. The laconic design of the model does not attract attention - externally the sensors resemble ordinary household switches.
KOMTECH/DD-IK 301	A universal model that fits into your home design	The model allows you to monitor the territory at 180⁰. The disadvantage of this option is the short distance - only 6 m. The disadvantage, however, is more than compensated by the protection factor - 44. Such a device is not afraid of natural manifestations. Interesting design, fitting into the concept of modern country house. The price is small - up to 560 rubles
Technolight/ ST12	The optimal choice for the garden and home	By analogy with the previous model, this motion sensor for turning on the light has a viewing angle of up to 180⁰, but with an impressive distance of up to 12 m. This increases the chances of protection - intruders will be noticed earlier. Interesting performance in black and white design. An acceptable cost - 520 rubles - and a high IP protection index - allow us to call the model optimal when choosing.
ASD/DD-020B-W	Disguised in a plasterboard ceiling, it is an independent interior item	Ceiling motion sensor with a 360⁰ view, fully compensating for a short range of 6 m. High price– 650 rubles – due to low energy consumption and stylish design(under the built-in lamp).

Expert opinion

“When choosing, they are also guided by other parameters of the detector - design (if required internal installation) and protection from humidity (respectively, external).”

How to install motion sensors to turn on the lights yourself

The low power of the sensors allows you to install them yourself, with known safety precautions - turning off the power supply, the presence of control tools (indicators). Each device is supplied with a diagram of a motion sensor for lighting and instructions with the described connection steps. Following them, installing and configuring the device is easy. So:

1. If sensor purchased with a built-in battery, then installation consists of making the right choice places for fastening and, in fact, the fixation itself to the wall or ceiling. With devices operating from a 220V network, the work is more scrupulous.
2. You should carefully inspect the detector housing. The letters L and N mean the working and zero phase, respectively. The connection to the lamp is connected to the working phase connector - the wire is stripped and fixed to. Even if there is a mix-up, the device will not be damaged, it will just not work.
3. Before installing a motion sensor to turn on the light, you need to apply voltage. If the indicator does not light up, then it makes sense to wait up to 1 minute - some models require time to “boost”. If everything is satisfactory, the sensor is attached to the surface using appropriate fasteners.

Device setup

Typically, the motion sensor housing has a setting knob with a specific scale or several switches - from 2 to 4 pieces. They have their own letter designations and direction of rotation. For example:

• LUX. Light threshold. Means the amount of daily or electric light, at which the detector does not work. To check, it is set to maximum, then according to needs.
• TIME. Response period and delay light signal. After the specified time has elapsed, the sensor turns off. If the movement continues, the device turns on the lighting again. Initial setting to minimum.
• SENS And MIC. Sensors and microphone - respectively. Settings are on infrared, ultrasonic and combined models. The first parameter is adjusted to the maximum value, the second – to the minimum.

“If you want to make the sensor inconspicuous, it is important to choose a location for it in advance. In case of incorrect position, covering or masking it with something is not recommended. This reduces the sensitivity of the device.”

Useful recommendations before connecting a motion sensor for lighting

For durable and, most importantly, quality work, it is important to observe several points before connecting motion sensors for lighting and after:

1. Plastic instrument cases are fragile. The polymer lens is particularly sensitive - important element detector optics. The fragile system must be handled with care before and after installation.
2. External motion sensors for turning on lights often burst in the cold or become deformed from direct contact sun rays. It is better to avoid such installation locations. As well as excessive humidity. If there are no protected places, visors are installed above the devices.
3. Internal sensors are not located near or household appliances with UHF technology, infrared radiation and other features that may cause interference. The maximum proximity is described in the instructions.
4. Sensors must not be installed with incandescent lamps. The effect will be permanent, since the thread does not cool down immediately, and the device, designed for temperature changes, will regularly send a signal to activate electricity. “Light music” is provided.

Initial setup home sensor movement to turn on the light does not guarantee complete safety. You will need to adapt the system completely to your own lifestyle - the presence of a stranger, and not animals or the fluttering of leaves in the wind. If you are not completely confident in your abilities, it is better to use the services of professionals. They will provide reliable results.

As a result

So, the algorithm for your own safety or home property is as follows:

1. Select a suitable sensor, focused on heat, motion, or ultrasound of a moving body.
2. Calculate the location for installing the selected option. It must be protected from external manifestations by a visor. If you need to mask the sensor, the location is chosen in advance - you cannot cover the device, this will reduce its activity or completely block it.
3. Carry out installation in accordance with the instructions. If there is not enough knowledge (although no special knowledge is required) or there is no time for independent work, you should turn to professionals.
4. Set initial setting. Based on the results, adjust the sensor to your own needs.

There are practically no difficult moments. And confidence in one’s own safety and in one’s “earned by back-breaking labor” will increase.
