Distance Measurement Using Ultrasonic Sensor And Arduino Uno Code

1 ultrasonic sensor hc sr04 procedure.
Distance measurement using ultrasonic sensor and arduino uno code. It acts as a sonar. 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. And then perform calculations and displayed result on 16x2 lcd by using appropriate functions. So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor.
Distance measurement using ultrasonic sensor and arduino uno code. 1 arduino uno r3. Open the arduino ide software on your computer. Find more about the working of distance measurement project in this tutorial.
In code we read time by using pulsein pin. Follow the circuit diagram and make the connections as shown in the image given below. Arduino ultrasonic sensor code for distance measurement. Hc sr04 ultra sonic sensor.
Coding in the arduino language will control your circuit. Distance measurement using ultrasonic sensor. Download the i2c lcd library. It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.
In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04. Working of ultrasonic sensor. The ultrasonic sensor is used to measure the distance. The module sends 40 khz signals automatically and then detects whether the pulse is received or not through echo.
Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.
