The HB100 microwave module is a microwave moving object detector designed by the principle of Doppler Radar.

The HB100 is a microwave motion sensor that uses the Doppler effect to detect moving objects. The output signal from the HB100 has a low gain. This project is an amplifier circuit specifically designed to amplify the signals from the HB100 sensor, resulting in an output signal with a higher gain that can be used directly by a microcontroller for detection purposes. This module features power and signal indicator LEDs.
