ESP32 Arduino: Using an infrared CO2 sensor techtutorialsx

May 03, 2018· The Analog Infrared CO2 sensor allows to measure the CO2 air concentration in a range from 0 to 5000 ppm (parts per million), with an accuracy of ± 50ppm + 3% of the reading [1]. The sensor operation is based on the NDIR technology (nondispersive infrared) and includes temperature compensation [1].


CO2 Monitor Arduino Project Hub

And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a function of relative humidity and temperature is equal for CO2 …
