No.

What else do I have to do to enable sensor support?
You need to read QtMobility docs. I suspect giving you a direct answer would not help you with anything as you'd come back again in 10 minutes with a next problem related to not reading the manual prior to using some solution.

Is there anywhere easy instalation of Qt Mobility? When I select configure file in Qt Mobility open source *.rar file it shows cmd window for a moment and it doesn't install Qt Mobility. And "nmake" and "nmake install" commands don't work.
I've never heard of any rar file containing Qt Mobility so I can't help.
