How does an NDIR CO2 Sensor Work? |

An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR radiation produced by the lamp is very close to the absorption band of CO2.

Direct Optical Carbon Dioxide Sensing Based on a Polymeric …

A novel optical method for the determination of CO2 concentration in aqueous and gaseous samples of plasticized PVC film is presented. The detection principle makes use of a direct molecular recognition of the carbonate ion by a molecular tweezer-type ionophore, which has previously been demonstrated to exhibit excellent carbonate selectivity. The carbonate ion is extracted together with hydrogen ions into …
