Carbon Dioxide Sensor MH-Z19b - Part 1 - Hardware design ...

2019-06-10· Some time ago I have purchased online carbon dioxide (CO2) sensor module MH-Z19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 400-1000ppm. Higher levels lead to various negative effects like a feeling of “bad air” and so on. The concentration of 2000 ...

Tindie Blog | A CO2 Sensor for ESPHome

2020-08-13· The MH-Z19B is a pretty neat sensor. It uses non-dispersive infrared to detect the concentration of CO2 in the air. This makes it pretty immune to the percentage of oxygen in the air, and with no moving parts or chemical sensor elements it should have a fairly long lifespan. It can detect concentrations up to 5000 ppm, at which point most humans are unable to focus well, complain of …
