The arbiter should call granted if no other user has been granted the resource. The arbiter code is pretty well tested, so the problem should be somewhere else. Can you double check that the string used to instantiate the arbiter is the same as the argument of unique in the file where the arbiter is wired?
If you can't get the arbiter working, just discard the arbiter code temporarily and make sure that you never read the temperature and the humidity concurrently. I'm sorry, but I can't work on this at the moment. It would be kind of cumbersome without the hardware, anyway.
