As described above, MOS type gas sensors change resistance (R) as a result of a change in adsorbed oxygen concentration. If this is used adequately, one can detect reducing gases like carbon monoxide. The adsorbed oxygen formed in clean air will be consumed on contact with carbon monoxide, the resulting decrease of R being used to estimate the concentration of carbon monoxide. The sensor ...
