Measuring CO2 with MHZ19B on ESP32 with MicroPython. In the previous posts, I described a simple weather station that measures temperature and humidity and sends the measurements to a Google sheet. The system is supposed to be used at home. Therefore, one of the next possible improvements can be measuring air quality in a room. That can be done, for example, by adding an MHZ19B …

MHZ19 MHZ19B

The English datasheet for the nonJST MHZ19B version: MHZ19B NONJST. The Chinese datasheet for the JST MHZ19B version (more detailed): MHZ19B JST. 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 ...
