    Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit.

    The basic principle of work:

    • Using IO trigger for at least 10us high level signal.
    • The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
    • IF the signal back, through high level , time of high output IO duration is the time from sending ultrasonic to returning. 
    • Test distance = (high level time×velocity of sound (340M/S) / 2.
