Motion sensors are one of the most important elements of modern lighting systems. They allow for reducing electricity costs and saving time when we are not in the room. But do you know how these sensors work?
Motion sensors can be of different types, but all of them work based on detecting the movement of an object in their range. The most common motion sensors use infrared radiation, which reflects off objects in the sensor's range and returns back to the sensor.
When the motion sensor detects a change in the reflection of infrared radiation, it turns on the lights or other devices, depending on its purpose. This allows for saving electricity and providing comfortable lighting in the room.
Motion sensors can be used not only for lighting but also for other purposes. For example, they can be installed on doorways to detect people entering or leaving a room, as well as for security purposes, such as detecting motion in the room during nighttime.
