When a heat-emitting object, such as a person or vehicle, enters the motion sensor's field of view, the light activates for a duration of 5 seconds to 6 minutes (adjustable in the field). During daytime hours (when used outdoors), the built-in photocell prevents automatic operation, conserving energy. The microwave occupancy sensor employs ultra-high-frequency radio waves and utilizes the Doppler Effect to detect motion effectively. This extremely safe method involves bouncing radio waves off nearby surfaces before returning them to the sensor. Please note that this motion sensor is not compatible with dimmable circuits.
