- 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!

Is there anyway to tell the sensor to stay on? I find that if I don't move around the lights go off when I don't wish them to.by Mary M. from home PA on 08-20-2012
The Watt Stopper WS-250 has a adjustable delay timer that can be set from 30 seconds to 30 minutes based on your preference. You may want to test several timed delays to optimize energy savings while eliminating issues with lights turning off early.
