When we start talking about motion sensors, we must remember that there is some confusion in terms. The fact is that the actual motion sensors are devices for working as part of security systems. And motion sensors for turning on the light are actually called light sensors, however, in everyday life, both devices are called motion sensors.
What is the main purpose of motion sensors to turn on the light? Comfort? Of course, but first of all, such sensors are installed to save energy. Thanks to them, electricity costs are reduced from 30% to 60%.
Their presence is relevant both in residential and non-residential premises, since the light comes on only when a living object appears in the zone of their action. As soon as the movement stops, after a set time, the light automatically turns off.
Also, the presence of sensors allows you to extend the life of the bulbs, as they work less and burn out less often. Sensors are also convenient in that the light will not be on all the time if you forgot to turn it off and left the house or even left for a long time.
The principle of operation of the sensors is the same regardless of the manufacturer. But they may differ from each other in some characteristics, which must be taken into account depending on the purpose of installing the device.
Which of the motion sensors offered by manufacturers for turning on lights can be considered the best on the market in 2021? By what parameters should you choose it and what to look for?
Editor’s Choice
ORB OB134920
The infrared sensor reacts to the appearance of people or animals. You can program it with the remote control. The device operates from the mains, including lighting when an object is detected within the range. The device can operate at high temperatures (up to 40 º C), the minimum operating temperature is ー10 º C.
The editors chose this sensor as the best for several reasons. First of all, it has high power, which allows you to connect more light sources to it than to other standard sensors. Another major advantage is that it can be placed at a high height, up to 12 m, which means that the sensor can be installed, for example, under the roof of a two-story house. A high degree of moisture protection makes it possible to use the device outdoors (but only in the warm season), and a large 360 ° viewing angle allows you to cover a large area.

How to choose a motion sensor
For help in choosing a motion sensor to turn on the light, Healthy Food Near Me turned to an expert – electrical engineering on local networks at commercial and industrial facilities to Yuri Slepukhov.
Popular questions and answers
2. The next option is operating range. Here you need to focus on the distance at which the sensor will have to work.
3. Next is viewing angle. Here everything will depend on the location of the sensor. If it will be installed in a narrow room, such as a corridor, a small angle is sufficient. If in a large wide room with several inputs, then one sensor with a large angle, preferably 360 degrees, otherwise there will be uncovered areas and errors in operation.
4. You also need to pay attention to whether there is adjustable sensitivity level. The presence of this function is important when installing in a room where there are animals. When installing the sensor outdoors, the presence of this function is always important, otherwise the device will be triggered even by small moving objects, such as frogs or mice.
5. Next – мощность. The higher it is, the more light sources can be connected to the sensor at the same time.
6. And the last thing you need to pay attention to – light level adjustment. If there is no regulator, the sensor can only be installed where the light level is the same throughout the day. For example, in blind corridors, staircases without windows, basements, etc.
As a standard, motion sensors are installed at the entrances above the doorways or on the ceiling above the door. One sensor is enough for each input. Devices are also installed on stairs, on each flight and in walk-through rooms, for example, corridors. The required number of sensors will depend on the layout features, for example, if there are corners and turns, it must be taken into account that the sensor will not respond to a moving object outside the zone of its sensitivity angle.
When installing motion sensors, it is important to exclude objects from their detection zone that can lead to erroneous operation – air conditioners, fans, etc.
There are also devices that include several motion sensors and a control unit. They integrate with each other and work co-dependently. If one of the sensors is triggered, the signal is transmitted to the control unit, and all lighting devices connected to this unit are turned on.
When installing the device on the street, the desired angle of its sensitivity will depend on the design features of the buildings. Depending on this, you will need one or more sensors.
Motion sensors differ among themselves in the way of installation: overhead and built-in. Provided that the characteristics of the devices are the same, the choice can be guided only by the design.
Detailed instructions for adjusting the sensor can be found in the user manual that comes with the kit. But, according to the expert, for the correct operation of the device, a specialist must install and configure it.
