Distance Measurement Using Ultrasonic Sensor And Arduino Pdf

How to measure distance using ultrasonic sensor hc sr04 and arduino.

Distance measurement using ultrasonic sensor and arduino pdf.

The experimental setup and results are described and explained. Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor. An ultrasonic distance measurement is a non contact distance ranging technique. 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.

Types of ultrasonic sensors available in market applications of ultrasonic sensor. The measured distance is calculated using arduino controller within a pre defined time interval. Here we are using a high precision hcsr 04 ultrasonic sensor module for the arduino based distance measurement. It is simply based on using the echo.

The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. 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. 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. A 16x2 lcd is connected with arduino in 4 bit mode.

The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino. Distance measurement using ultrasonic sensor and arduino uno r3. In this paper distance measurement of an obstacle by using separate ultrasonic transmitter receiver and a microcontroller is presented.

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 consists of transmitter and receiver modules. Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor. The sensor measure the distance around the sensor.

That is calculating the distance by analysing the time required for the propagation of sound waves. What is ultrasonic sensor. Ultrasonic sensor arduino circuit diagram and explanation. The servo motor rotates rotate in clockwise and anticlockwise direction.

Distance measurement using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely.
