A motion sensor light basically works by turning the lights on when the sensor detects any type of presence within the perimeters of the area it covers.
There are two basic reasons why people use this type of lighting device: first, it helps save on energy as the light automatically shuts off when it does not sense any presence in the room or within its perimeters; and second, it provides additional security for homes.
When someone gets too close to your home, the light automatically turns on, illuminating the stranger and thereby enabling homeowners to see who is lurking by the gate or the yard.
