Inspired by a simple ultrasound emitter/detector I saw at a tradeshow, I want to create one with a wide FoV. I can't be the first to want to do this, have you ever seen a project like this? If so, please post a link.
My project requirements:
1. A field of view (FoV) of 90 degrees or higher.
2. Low power, battery operated.
3. Microprocessor optional.
Zero
