The ultrasonic sensor is consists of transmitter and receiver modules.

Distance measurement using ultrasonic sensor and arduino pdf.

Distance measurement using ultrasonic sensor and arduino uno r3. The experimental setup and results are described and explained. Ultrasonic sensor arduino circuit diagram and explanation. Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino.

Distance measurement using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely. It is simply based on using the echo. The servo motor rotates rotate in clockwise and anticlockwise direction. Types of ultrasonic sensors available in market applications 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 hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. In this paper distance measurement of an obstacle by using separate ultrasonic transmitter receiver and a microcontroller is presented. In circuit connections ultrasonic sensor module s trigger and echo pins are directly connected to pin 18 a4 and 19 a5 of arduino.

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

Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor. Programming and hardware part of ultrasonic sensor interfacing with arduino uno r3 and at the end of this article you will learn its famous use in distance measurement. 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 measured distance is calculated using arduino controller within a pre defined time interval. An ultrasonic distance measurement is a non contact distance ranging technique. A 16x2 lcd is connected with arduino in 4 bit mode. Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.

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