Look at setSensorAltitude() and/or setAmbientPressure()
implemented setSensorAltitude() and it is in testing
scd40 branch implemented setSensorAltitude() and a power management change, but I'm not sure the current code has any other calibration issues that can be addressed in software.
From Sparkfun site: "Note: The SCD40 has an automatic self-calibration routine. Sensirion recommends 7 days of continuous readings with at least 1 hour a day of 'fresh air' for self-calibration to complete."
We could also look at case design, but I don't think there is a significant issue?
SCD40 is samping ~ 4F higher than external sensor sitting next to it. Need to check with calibrated sensor to determine which sensor is inaccurate, and if SCD40, look for calibration API
