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.
Distance measurement using ultrasonic sensor and arduino pdf.
Ultrasonic sensor arduino circuit diagram and explanation.
It is simply based on using the echo.
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.
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.
Here we are using a high precision hcsr 04 ultrasonic sensor module for the arduino based distance measurement.
An ultrasonic distance measurement is a non contact distance ranging technique.
The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance.
The servo motor rotates rotate in clockwise and anticlockwise direction.
The measured distance is calculated using arduino controller within a pre defined time interval.
That is calculating the distance by analysing the time required for the propagation of sound waves.
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.
