One of my pet peeves is people leaving the light on after they leave the room.
Leviton’s IPS02 Occupancy Sensor Switch automatically turns the lights on when you enter a room and off when you leave. Sensors have 180-degree span to scan the entire room, or you can program it to scan only a certain area.
Another feature is a manual on and off switch. So, if they do remember to turn the lights off, all they have to do is hit that switch. It’s a perfect solution for saving energy on your power bill.
It is available at The Home Depot.
