Ultrasonic Sensor Arduino Project

Ultrasonic sensor hc sr04 is a sensor that can measure distance.

Ultrasonic sensor arduino project.

Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm. Ultrasonic sensor arduino circuit diagram and explanation. The setup is now ready. Connect the vcc and gnd.

A 16x2 lcd is connected with arduino in 4 bit mode. The data is processed using processing and the distance is marked. It allows to detect a presence or to measure a distance via ultrasounds. The modules includes ultrasonic transmitters receiver and control circuit this is a simple example of using the ultras.

It emits an ultrasound at 40 000 hz 40khz which travels through the air and if there is an object or obstacle on its path it will bounce back to the module. Find these and other hardware projects on arduino project hub. Simple project with the ultrasonic sensor hc sr04 led arduino tutoriel. In one of our previous arduino project we used the sensor hc sr04 to allow a robot to see obstacles while moving and to act accordingly the hc sr04 is a very popular ultrasonic sensor and you should definitely learn how to make use of it.

The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. This project will show you how to use an ultrasonic sensor with an arduino. Connect the positive terminal with pin 8 of arduino and negative terminal to gnd. Connect the trigger pin to pin 12 and echo pin to pin 13 of arduino.

Now load the code in arduino ide and then upload it to arduino. 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. The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. In this project i will show you how to use two ultrasonic sensors connected to your arduino board.

Obstacle distance is measured using ultrasonic sensor and arduino. What is an ultrasonic sensor. An ultrasonic sensor is a module which uses ultrasound you didn t expect that did you. This project uses an ultrasonic distance sensor to create a pocket of wave interference where a small object can be levitated.

I m providing a full step by step guidance to expalin how to use this kind of sensors and i m explaining in details both hardware and software parts in order to turn this guidance the simplest way that leads you to try your own skills in electronic making. Ultrasonic rangefinder with processing.
