The most common CO2 sensors are known by the engineering term Non-Dispersive InfraRed, or NDIR. An NDIR CO2 sensor shines infrared light through a gas sample in a sample chamber. Sensitive photo-detectors measure the intensity of the infrared light after it passes through the gas sample. CO2 molecules are opaque to micron infrared light while the rest of the air molecules are not. So the ...
