Ultrasonic Distance Sensor

by Frederick Bryan, Clemson Electrical Engineering Student

Short Background

In road vehicles, ultrasonic distance sensors are commonly used as the distance sensor in low-speed, close distance detections, such as that need in back-up sensing and parking systems.

In the video that follows, I demonstrate my own distance sensor using the Arduino microcontroller and a MaxBotix Maxsonar sensing device. Links to the manufacturers' website are found below.

For more information on how to build your own version of this project, please see the "For More Information" links, links which I used while developing this project.
