Re: Ultrasonic Help
I've used these sensors many times, and I don't think they're going to reliably give you the feedback you're looking for. I think an encoder with some limit switches to 'zero' the position (or set it to whatever encoder value makes sense for where the limit switch is) would probably be much more reliable. Depending on the mechanism, it may also be feasible to have a multi-turn pot where the encoder would mount, so it has sufficient travel range to sense the full movement of the elevator. This would always give you an absolute reading.
