Handheld Ultrasonic Rangefinder

Handheld Ultrasonic Rangefinder

by Vincent Ng and Jerry Wang

ECE 476: Spring 2004


Our ultrasonic rangefinder is capable of allowing the user to determine his or her distance from an object or wall.

When deciding on what type of project to design and construct, we decided that we wanted to create something that would have some practical use in life. Many groups in the past created video games, but we wanted to be different. We considered issues such as safety, user interface, and ease of use, and came up with the idea of making an ultrasonic rangefinder. A rangefinder can be used in various applications such as a measuring device or an obstacle detection device.
