Illuminate an office, classroom, restroom, or closet automatically with this passive infrared wall occupancy sensor. It detects body heat in motion, and automatically turns lights On and Off as people enter and leave a space. Mount it where full line-of-sight is possible. By reducing the amount of time the lights are on, the sensor can help cut energy consumption and significantly reduce energy costs. It also features an integrated photocell that can keep lights off when sufficient daylight is in a room.
