The ENERLITES HMOS-J-W is a motion sensor wall switch that operates lights using passive infrared (PIR) technology. The motion sensor features a 180° field of view to provide up to 700 sq.ft. of coverage area. The sensor has 2 modes and operates lights ON/OFF based on occupancy or vacancy in the area. In occupancy mode, lights turn ON automatically when motion is detected, and turn OFF after no motion has been detected for the pre-selected time delay
