The product is a new saving-energy switch; it adopts microwave sensor with high-frequency electro-magnetic wave (5.8GHz), integrated circuit. It gathers automatism, convenience, safety, saving-energy and practicality functions. The wide detection field is consisting of detectors. It works by receiving human motion. When one enters the detection field, it can start the load at once and identify automatically day and night. Its installation is very convenient and its using is very wide. Detection is possible through doors, panes of glass or thin walls. Why Microwave Motion Sensor? Quick response time, Higher accuracy than PIR, Don’t affect temperate, wide range, Detect outside glass or other thin material Now Switch ON/OFF your Lights, Bulb,CFL, etc by AUTOMATIC Use Microwave Motion Sensor Life: More than 5 years
