MH-Z19 & MH-Z19B

The English datasheet for the non-JST MH-Z19B version: MH-Z19B NON-JST. The Chinese datasheet for the JST MH-Z19B version (more detailed): MH-Z19B JST. Auto Calibration: The MH-Z19 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 ...
