The basic principle of work: (1) Using IO trigger for at least 10us high level signal, (2) The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back. The modules includes ultrasonic transmitters, receiver and control circuit. Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. Ultrasonic sensor can detect movement of targets and measure the distance to them in many automated factories and process plants.
