Ok guys.. I was thinking about adding some backup sensors to my car.
I have some experience in robotics using sonar sensors so was just going to use those, but they are anywhere from $20 to $80 a piece! and they arnt weatherproof either. I then sumbled across this..


it has 8 sensors (and a bunch of other crap I probably wouldnt use) but the 8 sensors alone seem to be worth the price. Does anyone know anything about these sensors? I am just assuming they are analog output since they are so cheap.

The idea is if they are analog, I could just pipe them into a Parallax Basic Stamp micro controller to send the values to my carPC.

I guess the main question is.. does anyone know anything about these sensors? where they are made? anything?
