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
