Q » How does motion sensor lighting work?
01 Nov, 2025
A » Motion sensor lighting operates using sensors that detect movement in a designated area. When motion is detected, the sensor sends a signal to the light fixture to turn on. These systems typically use passive infrared (PIR), ultrasonic, or microwave sensors. PIR sensors detect body heat, while ultrasonic and microwave sensors emit sound waves or microwaves that bounce off objects to identify motion, providing energy efficiency and convenience.
