A Sensitive DIY Ultrasonic Range Sensor

Posted by Simon Wood on January 25, 2011 at 12:30pm

Spotted over on Hack-a-day, would be great on a quadcopter.

I needed some ultrasonic range finders for my project. But most of the commercial sensors like Parallax’s PING sensor and other similar products are quite expensive, especially if multiple units are needed. So I thought why not building it myself?

Quite cool. Perhaps a motor driver IC (or audio amp) could be used in place of a discrete bridge?
