Ok just going to jump in at this point. If we are talking Aliens
(i.e. the film) then in the first one the motion sensor was based on
changes in air density (if memory serves correct). So presumably
just moving through an atmosphere was enough. (i.e. don't fight in
a vacuum :)

Also how about if motion detectors were based like some animals
in picking up electrical discharges from muscles when they are used.

Ok that's it :)
