Which sensor?
I need a sensor much like a potentiometer, but one that measures linear distance instead of rotation. For example, one that I could attach to a pneumatic cylinder to know where it is.
While browsing the Digikey catalog for something that would work, I came across a "Distance Measuring Sensor" from Sharp. Has anyone used these? Would this do what I need, and could I just run it to an analog input?
