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 ...

The MHZ19B carbon dioxide gas sensor (hereinafter referred to as a sensor) is an intelligent allpurpose small sensor that uses the NDIR principle (nondispersive infrared) to detect the presence of CO2 in the air with good selectivity and anaerobic properties of gas dependence, long service life and other properties. Builtin temperature compensation. Simultaneously with serial output ...
