Ultrasonic Sensor Module Technical Specification1,Product synopsis

ultrasonic sensor is  non-contact distance  measurement  module,  which is also compatible  with electronic  brick.It’s  designed  for  easy  modular  project usage with industrial performance.

2,Product principle

Ultrasonic ranging module provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 2mm. 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
