 If you are sourcing a ultrasonic ranging module , the HC-SR04 is good choose . Its stable performance and high ranging accuracy  make it a popular module in electronic market .


Compared to the Shap IR ranging module , HC-SR04 is more inexpensive than it . But it has the same ranging accuracy and longer ranging distance.


 Specifications:

  • power supply :5V DC
  • quiescent current : <2mA
  • effectual angle: <15°
  • ranging distance : 2cm – 500 cm
  • resolution : 0.3 cm

There are 4 pins out of the module : VCC , Trig, Echo, GND . So it’s a very easy interface for controller to use it ranging. The all process is : pull the Trig pin to high level  for more than 10us impulse , the module start ranging ; finish ranging , If you find an object in front , Echo pin will be high level , and based on the different distance,it will take the different duration of high level. So we can calculated the distance easily :

Distance = ((Duration of high level)*(Sonic :340m/s))/2
