Distance Measurement Using Ultrasonic Sensor And Arduino Code

That is calculating the distance by analysing the time required for the propagation of sound waves.

Distance measurement using ultrasonic sensor and arduino code.

The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. The ultrasonic sensor is consists of transmitter and receiver modules. It is simply based on using the echo. Check this project using oled display.

Ultrasonic sensor arduino circuit diagram and explanation. An ultrasonic distance measurement is a non contact distance ranging technique. A 16x2 lcd is connected with arduino in 4 bit mode. Distance measurement using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely.

What is ultrasonic sensor. The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor. Here we are using a high precision hcsr 04 ultrasonic sensor module for the arduino based distance measurement.

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. It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it. 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. The ultrasonic sensor is used to measure the distance.

It acts as a sonar. In circuit connections ultrasonic sensor module s trigger and echo pins are directly connected to pin 18 a4 and 19 a5 of 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.

Breadboard and jump wires. How to measure distance using ultrasonic sensor hc sr04 and arduino. Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor. In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04.
