Ultrasonic distance sensor 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.
Wire connectig direct as fallowing:
- 5V Supply
- Trigger Pulse Input
- Echo Pulse Output
- 0V Ground
Connectors are included so soldering on EMoRo2560 board is not necessary.
