CO2 Monitor Arduino Project Hub

The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. It may be written as: CO2 = 410*ppm* (Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to according to Mad Frog.

Gravity: Analog CO2 Gas Sensor | Arduino Official Store

This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF) will be released.
