Ultrasonic Sensor Arduino Project Code

Arduino ultrasonic sensor code for distance measurement.

Ultrasonic sensor arduino project code.

The setup is now ready. 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. Connect the positive terminal with pin 8 of arduino and negative terminal to gnd. Find more about the working of distance measurement project in this tutorial.

The ultrasonic sensor has four terminals plus 5v trigger echo and gnd connected as follows connect the plus 5v pin to plus 5v on your arduino board. Where speed of sound around 340m per second. Simple project with the ultrasonic sensor hc sr04 led arduino tutoriel. This is proect of arduino ultrasonic sensor.

You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Explore 68 projects tagged with ultrasonic. Now load the code in arduino ide and then upload it to arduino. The modules includes ultrasonic transmitters receiver and control circuit this is a simple example of using the ultras.

Connect gnd with gnd on arduino. We will use the serial monitor with this line of code. Connect echo to digital pin 6 on your arduino board. 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.

Select the port i e com3 and choose your arduino board type i e arduino uno genuino then compile it to your arduino. Speed of the ultrasounds. Serial print distance in cm. Check the serial monitor readings.

Ultrasonic sensor arduino 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. The ultrasonic pulses collide an object and leaves in the other direction the echo terminals receives the ultrasound pulses and the sensor calculates the distance based on the time of the pulses. Connect the trigger pin to pin 12 and echo pin to pin 13 of arduino. Distance measurement using ultrasonic sensor.

Ultrasonic sensor hc sr04 with arduino code for ranging testc c write your code in arduino ide software save it. Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm. In this project i will introduce you to the hc sr04 ultrasonic sensor. Find these and other hardware projects on arduino project hub.

It works by sending sound waves from the transmitter which then bounce off of an object and then return to the receiver. 340 meters per second.
