K58S55 5.8GHz Microwave Motion
Sensor

K58S55 is a compact microwave sensor, which is operating at ISM 5.8GHz band. It works on the principle of the `Doppler effect’. If a movement in the detection zone changes the echo pattern, the sensor responds and generate control signal to switch light on. The compact size, low power consumption, customized detection distance and time delay make K58S55 ideal for scenarios of smart lighting, security monitoring, intelligent control system.
