An ultrasonic distance measurement is a non contact distance ranging technique.
Distance measurement using ultrasonic sensor and arduino pdf.
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.
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.
Distance measurement using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely.
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.
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.
In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04.
How to measure distance using ultrasonic sensor hc sr04 and arduino.
The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do.
The sensor measure the distance around the sensor.
Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.
The servo motor rotates rotate in clockwise and anticlockwise direction.
The ultrasonic sensor is attached with the servo meter.
The measured distance is calculated using arduino controller within a pre defined time interval.
The experimental setup and results are described and explained.
The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance.
Ultrasonic sensor arduino circuit diagram and explanation.
It is simply based on using the echo.
