So you assume the CO2 is always the same? Or that the CO2 concentration is equal to that outside and you measure it? The CO2 concentration in the air must change with temperature and humidity?
What I am suggesting would help get more accurate results would be some form of anomaly detection or outlier rejection system but you would need to use a PC with an I/O board and some programming language.
