Gear Tooth Counter for height

[SeanTeags]

I was wondering if it is possible to use the gear tooth sensor to set predetermined heights for an elevator? for example, set it to go and stop at X amount of teeth that we know is the amount of rotations needed to get our elevator to level 1, 2 and 3 to more precisely place tubes on the pegs.

I have done research and I have found that people use it to determine relative speed, but we are not sure if it can be used this way... Can it?

I am aware that the sensor does not know direction

Thanks
