20170323· The cool thing about the MHZ14 and the even better MHZ19 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. So they are not very good in giving absolute values, but they are very good in measuring relative changes. These sensors have …
