The SK-805 5.8GHz Microwave Radar Sensor Body Motion HF Detector Light Switch is an active motion detector that emits high-frequency electro-magnetic wave and receives their echo. The sensor detects the change in echo from even the slightest movement in its detection zone, which is far more sensitive than infrared sensor. A microprocessor then triggers the switch. Delay time, detection distance and light sensor can be easily adjusted to meet your requirements. It is commonly used to control lighting and extract ventilation, helping to ensure that lights and fans are not left on.
