The Digital Infra-Red Rangefinding System turns the excellent Sharp series of analog-output IR sensors into a digital-talking sensor!
When the Sharp sensors disappeared, this project was shelved, but with their re-introduction, we've dusted off and improved the code and adapted it to the new version.
Remember the old Sharp GP2D02 sensors? They were pretty handy, accurately measuring the distance to an object, then sending it back to your microcontroller as a serial stream. Worked pretty good, except you had to have a conversion table to turn it into usable distance units. Ah, but then they went out of production. So long, poor GP2D02 - was nice having you!
But that wasn't good enough for us. It was a good idea, but needed more. So here it is: The Digital Infra-Red Rangefinding Plus (DIRRS+) Kit.
We take a Sharp GP2Y0A21 sensor, and add our own brains to it. Not only does it duplicate exactly what the GP2Y0A21 offered, it one-ups it by talking several ways to your microcontroller:
The DIRRS+ does not require the special "JST-3 Sharp" connector and cable. Use a standard 0.100" header, or solder wires directly to the module PCB!
If you have a need to measure distances with the precision of the excellent Sharp GP2D12 quickly and simply, without having to burden your micro with more math, this is the unit for you! Here's more specifics:
