This sensor can be programmed to activate when both PIR and ultrasonic technologies detect occupancy or when only the PIR sensor detects occupancy. After turning the light on, the programmed technology maintains the light on until it no longer detects occupancy and the 5, 15, or 30-minute delay passes. Simply install this occupancy sensor in a small enclosed area like an executive office, conference room, classroom, or break room to make your building run more efficiently and to save on energy.
