Re: What kind of sensor should we use?

Then you put in a little simple code to only run it for x.x seconds in one direction and y.y seconds in the other direction. Problem solved without sourcing a sensor or figuring out how to program it.
If I'm not mistaken, the window motors will auto-protect if they trip the internal thermal limit. The software timer would definitely be a good idea in this case.

OP, can you provide a simple sketch of your mechanism?
