A motion detector is a device that detects moving objects, particularly people. A motion detector is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
Motion detectors allow you to operate the light in the conventional, manual way, usually by flipping the switch off for a second, then back on. This allows you to keep the light on at night when you want to, even when thereâs no motion. By double flipping a second time, you return to automatic.
