South Georgia | If you switch from one type of sensor output to another, you'll have to change the code to be able to read the other sensor type.
The Maxbotix sensors linked earlier will do pulse width (aka PWM), analog voltage, and a couple different types of serial. I don't know what distances serial is reliable over, so I'm not sure about that. Likewise, analog voltage may have more issues with bad connections and 'noise' at the low voltages that we're talking about. I think PWM may be more reliable.
Disclaimer: I'm not an electrical engineer. I know just enough about what I'm talking about to sound like I'm smart. I don't know one bit more than that. If anybody who does know more about this stuff disagrees, I'd like to hear their viewpoint.
