Microwave Motion Sensor

Description

The HB100 is a small and compact microwave motion sensor based on the Doppler effect. It consists of a transmitting and a receiving section. As soon as the sensor is powered, it sends a train of pulses at a frequency of 10.525 GHz (low power); when they encounter an object, the train of pulses received by the module will be greater or lesser depending on the distance. It can be used for automatic opening of doors and electric gates, automatic switching on of lights, etc. Detection range about 20 meters.
