MH-Z19 CO2 sensor | MySensors Forum

2017-03-23· The cool thing about the MH-Z14 and the even better MH-Z19 is that they use light spectrum analysis. They send infrared light, and measure how much of that light is absorbed in the spectrum that CO2 absorbs in. While not very accurate, they are very precise.

CO2/Humidity/Temperature Sensor - Guillier

Until recently, gaz sensors were either analogue (and totally uncalibrated) or relatively expensive (when not both at the same time). Then came the MH-Z14 which is a affordable "Non-Dispersive InfraRed" sensor, in theory quite selective. The MH-Z19 from the same company can be found for ~ $25. The main issue is the partial documentation.
