The ultrasonic sensor is attached with the servo meter.

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. In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04. Ultrasonic sensor arduino circuit diagram and explanation. Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor.

The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. 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. Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino. In circuit connections ultrasonic sensor module s trigger and echo pins are directly connected to pin 18 a4 and 19 a5 of arduino.

The servo motor rotates rotate in clockwise and anticlockwise direction. How to measure distance using ultrasonic sensor hc sr04 and arduino. The measured distance is calculated using arduino controller within a pre defined time interval. 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.

It is simply based on using the echo. 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. Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.

What is ultrasonic sensor. The experimental setup and results are described and explained. The sensor measure the distance around the sensor. An ultrasonic distance measurement is a non contact distance ranging technique.

The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. Distance measurement using ultrasonic sensor and arduino uno r3. 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. The ultrasonic sensor is consists of transmitter and receiver modules.

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