MICROWAVE MOTION SENSOR is a compact motion sensor. It is intended for surface mounting.
The specific thing about motion sensors is that after the preset time has elapsed (10 sec. - 12 min.), the lighting in the room will turn off until it detects the next movement.
In order to trigger the sensor, there must be visual contact with the moving object.
Using the three regulators, you can set the sensor's light sensitivity, the detection distance, and the lighting duration of the lighting fixtures to which the sensor is connected.
