Ultrasonic sensor hc sr04 ultrasonic sensor hc sr04 sen 15569 this is the hc sr04 ultrasonic ranging sensor.

Hc sr04 arduino beispiel. Arduino with hc sr04 sensor. You will learn how to interface ultrasonic sensor hc sr04 with arduino. Library for hc sr04 ultrasonic distance sensor.

Library for hc sr04 ultrasonic distance sensor. Open the arduino ide software on your computer. Open a new sketch file by clicking new.

So here we provide an example on how to use the hc sr04 ultrasonic sensor with the arduino. This sensor is very popular among the arduino tinkerers. Like if statements switch case controls the flow of programs by allowing programmers to specify different code that should be executed in various conditions.

1 ultrasonic sensor hc sr04 procedure. Simple arduino and hc sr04 example. In particular a switch statement compares the value of a variable to the values specified in case statements.

After buying a hc sr04 from amazon i could not get it to work out of the box. Follow the circuit diagram and make the connections as shown in the image given below. 1 arduino uno r3.

Repository contents firmware arduino example code. Ardublog mi blog en español sobre arduino ardublog libreria para arduino del modulo ultrasonic ranging hc sr04. For example if the object is 20 cm away from the sensor and the speed of the sound is 340 m s or 0 034 cm µs the sound wave will need to travel about 588 microseconds.

When a case statement is found whose value matches that of the variable the code in that case statement is run. Things used in this project. It can be an ultrasonic range sensor or any purposes.

After spending far too long on this than i felt i needed to i decided to ma. We would like to show you a description here but the site won t allow us. Make sure to check the pin definitions and.

This code is licensed under creative commons share alike and attribution by j rodrigo. Ultrasonic sensor hc sr04 with arduino tutorial. In this project the ultrasonic sensor reads and writes the distance to an object in the serial monitor.

This economical sensor provides 2cm to 400cm of non contact measurement functionality with a ranging accuracy that can reach up to 3mm. How to plug the ultrasonic hc sr04 into the arduino using the example plugandplay. But what you will get from the echo pin will be double that number because the sound wave needs to travel forward and bounce backward so in order to get the distance in cm we need to multiply the received travel time value.
