Hi,

You Said:
---------
You can do linearization and compensation and calibration all in firmware and use a 10k NTC with good accuracy for ambient measuring.
---------

Well linearization and compensation may be handled in the code. But isn't calibratin done first using an ideally accurate instrument first then we can add the offset in the code for soft calibration.....

I ask more on calibration of TCs, please.
