Ultrasonic Ranging Module HC-SR04
[47054]
Separate quantity discounts may be applicable, see below. CHF 5.93

Stock: 7

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

Specifications:

  • Voltage 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 its 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
