The Watt Stopper WT-2200 Ultrasonic White Occupancy Sensors with Isolated Relay
The Watt Stopper ultrasonic occupancy sensors operate on 24VDC and automatically turn lighting systems on and off based on occupancy. The sensors use Doppler technology to sense occupancy. They broadcast high frequency sound waves into the controlled area. Movement in the area will cause the sound waves to return to the sensor at a faster or slower rate resulting in a Doppler shift and occupancy detection. When the ultrasonic sensor detects occupancy, it switches lighting on through a Watt Stopper Power or Slave Pack.
