Temp, Humidity CO2 sensor and library.

latest version I have is 1.03 - see attachment - but it is a long time since I edited in it. there may be some work in progress on some points in it.
Note that the calibration functions must be used careful and do not use them if you don't understand their impact.

#all disclaimers apply :wink:

If you have comments remarks let us know.
