Product features

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
