How does an NDIR CO2 Sensor Work? |

At the detector end, the remaining light hits an optical filter that absorbs every wavelength of light except the wavelength absorbed by CO2 molecules in the air sample tube. Finally, an IR detector reads the remaining amount of light that was not absorbed by the CO2 molecules or the optical filter. How is the CO2 level calculated?

How do carbon monoxide detectors work? - Explain that Stuff

2008-08-28· Metal-oxide detectors have open chambers containing sensors made of metal (tin or platinum) oxide. When there's carbon monoxide around, the metal oxide reacts with it: the carbon monoxide "steals" oxygen from the metal oxide, converting itself into carbon dioxide, turning the metal oxide into pure metal, and producing heat at the same time.
