Hc sr04 ultra sonic sensor.
Distance measurement using ultrasonic sensor and arduino uno code.
In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04.
Coding in the arduino language will control your circuit.
The module sends 40 khz signals automatically and then detects whether the pulse is received or not through echo.
And then perform calculations and displayed result on 16x2 lcd by using appropriate functions.
Find more about the working of distance measurement project in this tutorial.
Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino.
Ultrasonic sensors not only offer distance measuring utility without any physical contact but enable us to measure with no noise and light unlike laser based distance measuring instruments.
