Feature
- Measures the distance within a wide range of 2cm to 400cm
- Stable performance
- Accurate distance measurement
- High-density
- Small blind distance
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
Pin configuration
- Pin 1: Vcc(5v)
- Pin 2: Trigger pin
