D203B PIR Motion Sensor Previous 
HW-MS03 Human Body Microwave Sensor Module is a digital microwave sensor module for motion detection. It operates across a 2.4GHz to 5.8GHz frequency range and is designed for indoor sensing applications. The module is resistant to temperature, humidity, airflow, dust, noise, light, and dark interference. It provides wide signal coverage with no blind spots. The output signal is weak, so it should be handled with proper circuit design. Power stability is important for correct operation.
