Distance Measurement Using Ultrasonic Sensor And Arduino Code

So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor.

Distance measurement using ultrasonic sensor and arduino code.

It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it. Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino. Here we are using a high precision hcsr 04 ultrasonic sensor module for the arduino based distance measurement. Ultrasonic sensor arduino circuit diagram and explanation.

Distance measurement using ultrasonic sensor hc sr04 and arduino may 13 2016 arduino tutorials arduino code distance hc sr04 measurement meter sensor ultrasonic manoj r. The ultrasonic sensor is used to measure the distance. How to measure distance using ultrasonic sensor hc sr04 and arduino. It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package from 2 cm to 400 cm or 1 to 13 feet.

The ultrasonic sensor is consists of transmitter and receiver modules. Ultra sonic sensor is a device which is capable of transmitting and receiving ultra sonic sound waves out into the air and calculates the distance from the sensor to the obstacle by making use of the time required for the sound wave to reach back the sensor. Thakur the hc sr04 ultrasonic sensor is a very affordable proximity distance sensor that has been used mainly for object avoidance in various robotics projects. Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor.

What is ultrasonic sensor. The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. An ultrasonic distance measurement is a non contact distance ranging technique. 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.

Distance measurement using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely. The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. In circuit connections ultrasonic sensor module s trigger and echo pins are directly connected to pin 18 a4 and 19 a5 of arduino. Check this project using oled display.

A 16x2 lcd is connected with arduino in 4 bit mode. In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04. It is simply based on using the echo. That is calculating the distance by analysing the time required for the propagation of sound waves.
