The Watt Stopper CX-105 White Passive Infrared Occupancy Sensor

The CX sensors are ideal for large areas and can cover up to 2000 square feet of walking motion. By choosing the proper lens pattern for each application, the sensors can reliably cover large offices,computer rooms,classrooms, aisle ways, warehouses,and open offices where coverage cut-off is desired. Corner mounting to a wall or ceiling adds versatility and more control to the coverage. The units operate by turning lighting on when they detect the difference between infrared energy from a human body in motion and the background space.After the area is vacated and the time delay elapses, lighting automatically turns off.
