Occupancy sensors function as a type of motion sensor. They can act as a ceiling, corner, or wall switch that automatically turns the lights on or off. When the sensor detects movement, the occupancy sensor turns the lights on. When the room remains empty for a certain period of time, the sensor shuts the lights off.
HomElectrical carries a variety of occupancy sensors accessories for use with specified sensors, including:
Daylight harvesting sensors use a light sensor to detect the amount of daylight in a space. The sensor then adjusts the amount of electrical lighting in the room depending on the natural light available.
