Rating of manufacturers of motion sensors for lighting. How to choose a motion sensor to turn on the light. Ambient temperature and switching capacity

A motion sensor is an electronic device that detects and records the movement of an object in the detection zone. Due to their low cost and ease of use, such devices are used in systems burglar alarm, as well as for turning on various devices (lamps, etc.). To know how to choose a motion sensor, you need to understand their modifications and technical parameters.

Main varieties

There are several types of sensors that respond to the movement of an object. They work on different technical principles, but perform the same task. When detecting a moving object, it turns on a relay, to the contacts of which any external device can be connected.

Exist following types motion detectors:

  • Infrared sensor;
  • Ultrasonic sensor;
  • Radio wave sensor.

The infrared sensor uses a PIR sensor that responds to the thermal radiation of an object. Sensors of this type are characterized by low cost, reliability and are used both in security systems, and for controlling lighting and other household appliances.

Ultrasonic sensors emit a signal at a frequency above 30 kHz and work as an acoustic locator. Sensors operating on this principle have a limited range due to signal attenuation, and their operation also disturbs pets. Among other things, they cannot be used outdoors due to large number moving objects.

Radio wave sensors also work like a locator, but instead of sound waves they emit microwave microwaves. Microwave radiation is unsafe for humans and the cost of radio wave sensors is slightly higher than that of other systems.

For use at particularly important facilities they are used combined sensors, including an infrared detector and a radio wave sensor, located in a common housing and operating in parallel.

In and for control electrical appliances, the most widely used are infrared sensors. They have a wide capture area, good range and are absolutely safe for humans.

There are innovative promising developments using semiconductor lasers, but so far such devices are expensive and have limited scope applications.

Motion sensor selection criteria

When selecting a motion sensor great importance has what purpose it will be used for. Sensors used in lighting control systems and other household appliances have some Extra options, which are not available in security alarm devices.

A motion detector for security is selected based on the following main characteristics:

  • Sensitivity;
  • Detection zone angle;
  • Horizontal zone length;
  • Fixed movement speed;
  • Presence of an anti-sabotage zone;
  • Supply voltage;
  • Temperature range.

The sensitivity of a good motion sensor must be adjusted so that it does not react to pets. Some types of sensors have step adjustment, and some models are equipped with a trimming resistor, which can be used to fine-tune sensitivity. The angle of the detection zone is measured in degrees. Typically it varies from 90 to 120 degrees. The exception is motion detectors of the “Curtain” type, which create a narrow but horizontally extended zone. The length of the detection zone of conventional sensors can be 10-15 meters.

The sensors respond to the speed of an object moving from 0.1 meters per second, so very slow movement can fool the sensor.

Anti-sabotage zone – this is a detection zone directed vertically downward and preventing the possibility of damaging the sensor. For this purpose, most models have an additional lens in the lower part of the body.

The supply voltage usually does not exceed 12V, since this is the voltage produced by the power supply of the control panel. Infrared motion detectors are rarely used outdoors, so the operating temperature range is not important parameter. This does not apply to sensors designed to control lighting.

Sensors for lighting control

To know how to choose a motion sensor to turn on the light, you need to know some special parameters of such devices. Motion detectors for turning on lights or other equipment can be installed both indoors and outdoors, so you need to pay attention to the operating temperature range. must have a dust- and moisture-proof housing and an installation bracket that allows you to align desired zone triggering.

In addition to the viewing angle and the length of the detection zone, the sensors have the following parameters:

  • Sensitivity;
  • Light level;
  • On time;
  • Switching power.

Sensitivity determines the body weight to which the sensor will respond. This parameter is adjusted using a potentiometer on the sensor body. As well as in security sensors, the sensitivity is set in such a way that there are no false alarms on pets. The illumination level can also be adjusted. At the maximum position of the regulator, the sensor will operate at daytime, which is not required when turning on the lights, but may be important for turning on other devices.

If the sensor is designed to turn on the lighting, the illumination level is selected so that operation occurs only in the dark. By adjusting the on time you can set the interval during which the light will remain on. This time varies from a few seconds to several minutes. For user convenience, a regular switch can be installed parallel to the motion sensor. The switched power is indicated in the device passport and usually does not exceed 1.5-2.0 kW.

  • Price – 870 rubles.

Sensors of this type can be installed in rooms where it is necessary to localize a small detection zone. This is achieved by adjusting the operating range.

To find your bearings on which outdoor sensor to choose, you need to carefully read the product data sheet. If the motion detector will be installed outdoors, then the lower and upper temperature limits should be selected depending on the climatic characteristics of the region. Besides, outdoor sensor must have a housing that protects against dust and moisture. To assess the degree of protection there is

When purchasing a motion sensor to turn on the light, you should not take the first one you come across. To begin with, you should determine some significant parameters, the conditions for its future use, and depending on them, select a sensor with suitable technical characteristics. There are four main parameters, taking into account which you will not go wrong and will not be disappointed; these are the parameters:

    conditions environment;

    power of switched equipment;

    features of the response zone: the required viewing angle and range of the sensor;

    requirements for sensor response time and light level adjustment.

For different conditions environment, sensors with different degrees (classes) of protection are provided. The protection class shows how resistant the sensor housing is to dust and other physical influences, how protected it is from moisture, and therefore whether it can operate normally in rain or snow, etc. Thus, the most common motion sensors are the following protection classes: IP20 IP40 IP41 IP44 IP54 IP55.

IP20. A sensor of this protection class can operate reliably in dry conditions. indoors, that is, where there is no risk of moisture getting on its body. The body of such a sensor will withstand accidental touches, but the ingress of sand, for example, can damage it.

IP40. Such a sensor is protected from possible contact with sand and small particles about 1 mm in size, but is not protected from moisture, that is, it is again applicable only in dry rooms.

IP41. There is already protection from moisture here, i.e. the damp space of the room will not pose a threat to normal operation sensor If during operation even drops of condensate fall on the sensor body, its operation will not be disrupted.

IP44. The housing of such a sensor is protected from splashes; it can be used even in rooms with high humidity and on the street, for example, it is already protected from rain.

IP54. This degree of protection indicates that the sensor housing is protected not only from splashes, but also from settling dust, i.e. Even if some dust gets inside the sensor housing, its operation will not be affected.

IP55. In addition to protection from dust, the degree of protection from moisture is higher; even jets directed at the sensor are acceptable.

Once the required sensor protection class has been determined, it is important to pay attention to maximum power, which the sensor can switch. It's one thing to turn on a low-power LED spotlight or fluorescent lamp, and quite another thing is switching a lighting system, for example, a production workshop.

Having known in advance the power of the lighting equipment to be switched on, you can easily select suitable model motion sensor. The maximum switching power of such sensors usually ranges from 60 to 2200 W.

When choosing a product, we often encounter the fact that we do not fully understand all its characteristics. Gigahertz, amperes, range, graphics controller, SSD and frequency range - no matter what we are going to buy: headphones, a smartphone or a game console, we will be faced with a whole list of unclear properties.

If we do not fully understand everyday things, then what can we say about such complex devices as motion and presence sensors. They are not often encountered in everyday life, and therefore sometimes even the Internet does not help to fully understand all their subtleties.

Today we will try to make the sensors more understandable for ordinary buyers and explain what their specific characteristics affect.

Motion sensor specifications

Typically, the list of technical characteristics of a motion sensor includes:

  • mains voltage;
  • power consumption
  • detection range;
  • range (perpendicular, frontal, presence);
  • degree of protection;
  • anti-sneak protection;
  • dimensions;
  • ambient temperature;
  • body material;
  • switching capacity;
  • time settings;
  • sensitivity settings;
  • illumination level.

The required mains voltage, power consumption, dimensions and housing material are standard parameters for a technical device. There is no need to explain them.

With detection range, range, degree of protection, anti-sneak protection, ambient temperature, switching capacity, time setting, sensitivity setting and illumination level, everything is a little more complicated.

Range and detection range

Let's start with the first one. The range or is the space in which the sensor is guaranteed to detect a person. This parameter is measured in degrees and varies from 120 to 360.

Ceiling motion sensors have the maximum value; they see the entire room. Less -
at wall sensors. For obvious reasons, their detection range is reduced
and can be 120, 140, 180, 200, 230 or 280 degrees.

The detection range is related to the range parameter. If the first determines the viewing angle, then the range indicates the space in which the sensor sees the person,
in meters.

This distance is determined in three planes:

  1. perpendicular – a person moves tangentially to a circle in the center of which there is a sensor;
  2. frontal – a person moves directly towards the sensor;
  3. presence - a person works under a sensor, for example, sitting at a table.

By default, the first zone is the largest. For example, at the sensor it reaches
10 meters, the second and third – 6 and 4 meters respectively. For models of the PD4 series, it can reach up to 40 meters in diameter, for example, in .

The frontal range of such a sensor reaches 20 meters. This device does not have the smallest zone – presence, in which the smallest movements are recorded.

Which one to choose when purchasing?

To put it simply, for large premises without partitions and narrow spaces you need a motion sensor with a large detection area and range. For rooms with a lot of small areas or just small rooms, choose a sensor with a standard range of 10, 6 and 4 meters respectively.

Degree of protection and anti-sneak protection

Despite the fact that the names of these characteristics are similar, their essence is noticeably different. We have already talked about the degree of protection more than once in the blog. For example, in the material about.

(IP) is indicated by two numbers: the first is intrusion protection foreign objects(for example, small particles and dust), the second is protection from water. Sensor protection degree B.E.G. varies from IP 20 to IP 65. Sensors with a minimum degree are protected from penetration by fingers and similar objects, but are not protected from water.


Models with maximum indicator protection IP 65, for example, suitable for wet areas. A high degree of security for other sensors is achieved using special accessories.

Available in B.E.G. and “intermediate” options with IP44 and IP54 with protection against dust and splashing water.

Which one to choose when purchasing?

For a standard room, for example, a corridor or office, a sensor with a minimum degree of protection is sufficient. It is necessary to take care of increased performance indoors
With high humidity: bath, kitchen, basement or work areas (production workshops). Additional protection street sensors also need it.

Anti-sneak protection eliminates the possibility of moving under the motion sensor. This characteristic is inherent in street motion sensors with a viewing angle of less than 360 degrees.

Anti-sneak protection compensates for the smaller viewing angle of a sensor installed on a wall or corner of the house and does not allow unwanted guests to move freely under the sensor.

When purchasing an outdoor sensor, give preference to one that is equipped with this function. After all, a special lens that serves to control the area against sneaking, not only improves the detection area, but also gives additional functions dynamic shutdown delay for greater savings.

Ambient temperature and switching capacity

Ambient temperature in technical specifications The sensor is also a pretty clear indicator. It indicates the temperature at which the device will function normally, without interference or failure.

This characteristic applies to all B.E.G. sensors. the same: from -25 to +50 degrees. Such temperature range enough for the sensors to not work on their own cold winter and very hot summers.

The switching capacity of the sensor determines how many lighting fixtures can be connected to one device. It varies from 40 to 3000 W. Sensors with a switching capacity of over 2000 W switch powerful loads.

Time, sensitivity and light settings

Time, sensitivity and light settings are the only technical indicators, which may change during operation. They are configured manually
depending on the characteristics of the room.

Thus, the illumination level of the sensors varies from 2 to 2000 lux, while the recommended values ​​for different rooms these are: in passage areas - 75-200 lux, in work areas (offices
and offices) – 600 lux, when working with heavy eye strain – 1000 lux.

The shutdown delay time varies from 30 seconds to 120 minutes. He also has recommended indicators: for passage areas - 5 minutes, for work areas - 15 minutes.

The sensitivity level is also manually adjusted. If you set its value incorrectly, the sensitivity of the presence zone will decrease, and with minimal movements, the device simply will not work.

We have already talked in more detail about the proper setting of these parameters in the material “”. As for choosing a sensor, before purchasing, find out the parameters required for your room and purchase a device whose time settings and light level meet the requirements.

How to choose the right motion sensor?

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 increasing penetration into our daily life all kinds of technical innovations. 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 front door or at the gate.

It is also necessary to know that sensors for turning on street lights when movement occurs 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 do 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 for detecting movement and turning on lighting works on the principle of continuous monitoring of 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 clock.

Installation of the device

Street sensor connects to the electrical network in the same way as a regular 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. The connection takes place through a 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 we see, the choice street sensors, responding to movement by turning on the lighting, 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.
