Description:
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.
