MH-Z19 CO2 sensor | MySensors Forum

· It's mostly a chemical proces. 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.

· I'm using your "basic usage" example code verbatim with software serial. I'm using an Arduino Nano knock off, with the rx/tx pins heading to D10/D11, the MH-z19 powered from an external 5V source (a USB battery) to make sure it gets enough juice, and hte Arduino itself running serial to my PC via the natrive serial port.
