1 arduino uno r3.
Distance measurement using ultrasonic sensor and arduino uno code.
Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.
So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor.
It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.
The ultrasonic sensor is used to measure the distance.
Working of ultrasonic sensor.
In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04.
The high level signal is sent to 10 microseconds using trigger.
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.

Follow the circuit diagram and make the connections as shown in the image given below.
The module sends 40 khz signals automatically and then detects whether the pulse is received or not through echo.
