Distance Measurement Using Ultrasonic Sensor And Arduino Pdf

Here we are using a high precision hcsr 04 ultrasonic sensor module for the arduino based distance measurement.

Distance measurement using ultrasonic sensor and arduino pdf.

That is calculating the distance by analysing the time required for the propagation of sound waves. What is ultrasonic sensor. In this paper distance measurement of an obstacle by using separate ultrasonic transmitter receiver and a microcontroller is presented. A 16x2 lcd is connected with arduino in 4 bit mode.

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. Ultrasonic sensor arduino circuit diagram and explanation. Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.

It is simply based on using the echo. Types of ultrasonic sensors available in market applications of ultrasonic sensor. An ultrasonic distance measurement is a non contact distance ranging technique. Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor.

The ultrasonic sensor is consists of transmitter and receiver modules. 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 measured distance is calculated using arduino controller within a pre defined time interval. 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. The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. The experimental setup and results are described and explained. The servo motor rotates rotate in clockwise and anticlockwise direction.

Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino. The ultrasonic sensor is attached with the servo meter. 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 sensor measure the distance around the sensor.

Distance measurement of an object in the path of a person equipment or a vehicle stationary or moving is used in a large number of applications such as robotic movement control vehicle control blind man 39 s walking stick medical applications.
