[arm-allstar] pcsensor ---solution

[David McGough]

I agree that the temperature calibration of all of these sensors is
"ballpark" quality. These devices probably also aren't linear, as
temperature changes (e.g.: going from 0C to 100C).  So, simply adding in a
constant adjustment offset will probably only optimize accuracy over a
portion of the measurement range.

An adjustment table is probably the simplest solution.  I've already done 
this with other sensors I've used.  I'll dig up that code and send a 
follow-up.
