The WattStopper DT-300 Motion/Occupancy Sensor features dual technology occupancy sensor combines the benefits of passive infrared (PIR) and ultrasonic technologies. The sensor mounts on the ceiling with a flat, unobtrusive appearance and provides 360 degrees of coverage.

The WattStopper DT-300 Motion/Occupancy Sensor turns lighting on when both PIR and ultrasonic technologies detect occupancy. It can also work with a low voltage switch for manual-on operation. Once lighting is on, detection by either technology holds lighting on. When no occupancy is detected for the length of the time delay, lighting turns off.
