MH-Z19B M5Stack

Intelligent Infrared CO2 Module (Model: MH-Z19B)

MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output. It is developed by the

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 ...

CO2 meter using M5StickC -

15/10/2020· The CO2 sensor is MH-Z19B, NDIR type. Cause I’ve been working at home and being cooped up in my room, I decided to make a CO2 meter as a guide to ventilate my room. A MOX gas type that called CCS811 showed inappropriate results for measuring actual CO2 concentration, such as higher readings due to human farting, so I use a high-precision NDIR -type MH - Z19B in this case.

24/03/2021· Features about calibration (both MH-Z19 & MH-Z19B), detection range change (MH-Z19B) and ABC logic on/off(MH-Z19B) are implemented at version or later. I'm afraid I've just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 gas, also MH-Z19B module. If you have these devices or apparatus and try to use …
