Microwave Sensor
The microwave sensor is an active motion detector, it emits high-frequency electro-magnetic wave（5.8GHz）and receives their echo. The sensor detects the change in echo from even the slightest movement in its detection zone. A microprocessor then triggers the “switch light ON” command. Detection is possible through doors, panes of glass or thin walls. 
The product is a energy-saving automatic switch adopted integrated circuit and precise detecting components. It can be on when body detect it and will be off automatically after body leave. Its performance is stable. It can identify day and night. The light can turn on when body enter detection field and move, it can turn off automatically when body leave detection field .
