Follow the circuit diagram and make the connections as shown in the image given below.
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.
In code we read time by using pulsein pin.
The high level signal is sent to 10 microseconds using trigger.
And then perform calculations and displayed result on 16x2 lcd by using appropriate functions.
Distance measurement using ultrasonic sensor and arduino uno code.
So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor.
1 ultrasonic sensor hc sr04 procedure.
Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.
The module sends 40 khz signals automatically and then detects whether the pulse is received or not through echo.

Distance measurement using ultrasonic sensor.
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.
It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.
