Distance Measurement Using Ultrasonic Sensor And Arduino

An ultrasonic distance measurement is a non contact distance ranging technique.

Distance measurement using ultrasonic sensor and arduino.

Ultrasonic distance measurement is a useful tool in various applications lately. It is simply based on using the echo. That is calculating the distance by analysing the time required for the propagation of sound waves. Here we are using a high precision hcsr 04 ultrasonic sensor module for the arduino based distance measurement.

Distance measurement using arduino and ultrasonic sensor hc sr04. By doing some mathematical calculations with the output values we can also measure the speed and various other physical dimensions. This is an efficient way to measure small distances precisely. The basic principle of ultrasonic distance measurement is based on echo.

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. Ultrasonic waves are transmitted and whenever these strike an obstacle and return back in the from of an echo difference of outgoing sound and. Ultrasonic sensors are useful for measuring distances. In this project we have used the hc sr04 ultrasonic sensor with arduino to determine the distance of an obstacle from the sensor.

You can watch the following video or read the written tutorial below. Furthermore these instruments are cheap and more reliable even in daylight where laser based instruments often decrease their efficiency distance measuring instruments have been in use for centuries and improvements. Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor. The device also has applications in the field of robotics.

Ultrasonic distance measurement project using arduino. It can be used in various applications such as positioning locating dimensioning selecting level measurement controlling and profiling. So we only need to calculate the traveling time of both sounds means outgoing time and returning. Hc sr04 ultra sonic sensor.
