Intelligent Microwave Sensor Switch AC220V-240V Human Body Induction Sensor Corridor Photoelectric Sensor

Introduction More informations Click here to open The microwave sensor is an active sensor The HF sensor emits high frequency electromagnetic waves 5 8 GHz and receives their echoes power consumption less than 2 MW This sensor detects changes in the echoes and even small movements within its detection ran ge The microprocessor then triggers the lights up c0mmand Signals through the door glass plates and thin walls are likely to be detected Installation reminder The sensor switch has a blind spot in the center If it is installed in a small indoor environment such as a bathroom or kitchen try to install the position to the side or install it in the corner because the sensing area will be better otherwise the vertical center activity may not be sensed 1 Control principle The microwave sensor uses the Doppler principle to transmit and receive high frequency microwave signals accurately sense the movement changes of the object and to control the opening lighting and off extinguishing of the load lamps through signal amplification and intelligent recognition of the single chip program Doppler principle the principle of ra dar is widely used in aviation aerospace and military 2 Intelligent induction 1 When a person enters the sensing detection range within 16m diameter the load lamp lights up when the person passes the inductive detection range and the set delay time counts down the load lamp automatically goes out 2 When the person enters
