- That project sounds pretty fun to work on! I have seen sensors that are
essentially something like a retractable wire on a reel that has a
potentiometer attached to the wheel's hub that allows you to detect large
positional displacements. I think that I was searching for "linear
potentiometer" or "linear position measurement" when I came across them.
