What is CO2eq?

The CO2eq represents CO2 equivalent which is an estimation of the CO2 concentration based on a H2 measurement. The SGP30 gives a signal which is calibrated to Hydrogen (the H2_signal). Based on empirical correlations between H2 and CO2, a conversion factor between H2 and CO2 has been determined. CO2eq output is then given by the measured H2 concentration and the empirical conversion factor.
