The sensor is passive infrared and responds to heat radiated from human body motion. They mount on a ceiling and turn lighting ON either automatically with occupancy or manually using a low voltage wall switch and the manual on mode of a STEINEL power pack. After a period of time where no occupancy has been detected, the sensor switches lighting OFF.
