WattStopper WS-250-W Motion Sensor, Passive Infrared Wall Switch Sensor, 120/277V - White

WattStopper's Passive Infrared Wall Switch helps cut your electric bill as much as 60%. The cleverly designed switch turns lights on or off based on room occupancy and ambient light level, ensuring that the lights are only on when they need to be. The switch conveniently installs in place of most standard switches and will fit behind a standard wall plate. Its built-in light level sensor will keep the lights off when natural light levels are above a preset level of your choice. Lights turn off when a room is vacant, making unnecessarily lit rooms and the high costs they incur a thing of the past!
