Auto Calibration: The MHZ19 is a sensor that is designed to be powered on and rarely turned off. The sensor calibrates over time (if autocalibration is on) using the lowest CO2 observed in the prior 24 hours). After 3 weeks, a value is stored with an accuracy rating, this can be requested using getAccuracy(). ABC must be disabled each day, however this is handled by the library. Calibration ...

This page is about the MHZ19 CO 2 sensor and some experiments done with it. This sensor gives a digital (serial) output of the CO 2 concentration in air, in partspermillion (ppm). It uses the optical measurement principle of measuring CO 2, which should be much more accurate than the inexpensive electrochemical sensors you can find. As far as I know, the optical measurement principle uses ...
