Introduction

The HC-SR04 Ultrasonic Sensor is a very affordable proximity/distance sensor that has been used mainly for object avoidance in various robotics projects . It essentially gives your Arduino eyes / spatial awareness and can prevent your robot from crashing or falling off a table. It has also been used in turret applications, water level sensing, and even as a parking sensor.

Specification

  • power supply :5V DC
  • quiescent current : <2mA
  • effectual angle: <15°
  • ranging distance : 2cm – 400 cm
  • resolution : 0.3 cm

Working Principle

There are 4 pins out of the module: Vcc , Trig, Echo, Gnd. So it's a very easy interface for controller to use it. Below is the flow of the process:

  1. Pull the Trig pin to low level for 2 us
  2. Pull the Trig pin to high level for 10us
  3. Pull the Trig pin to low level again
  4. Check the Echo pin for high level
  5. If there is an object in front, Echo pin will go to high level
  6. Based on the distance, the Echo pin will go high after a different duration.
