Motion sensor light switch, also known as light sensor switch, or occupancy sensor switch, is a motion-activated switch that controls the light automatically for you. The motion sensor switch turns on the light when the built-in motion sensor detects your presence in the room and turns the light off when the room is vacant.
It’s a convenient way to add lighting automation to your home with a hands-free, no-touch lighting experience. Moreover, motionsensor switches help homeowners save energy easily by preventing electricity waste from lights left on.
