Does a sharp Ir range finder sense movement?

All it does is sense distance to an object in front of it. You could correlate that to movement by looking at change in distance, but no, it does not work like an IR alarm motion detector.

No, just distance. But, you can write the code for the processor that could detect the difference from one distance measurement to the next.
