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 ...
NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. 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.

An optical sensor is placed inside, it uses the principle of non-dispersive infrared absorption (NDIR). The CO₂ molecules present in the measurement chamber absorb some of the infrared radiation emitted by the sensor. The radiation attenuation is therefore directly proportional to the amount of CO₂.
This ability to absorb and re-emit infrared energy is what makes CO 2 an effective heat-trapping greenhouse gas. Not all gas molecules are able to absorb IR radiation. For example, nitrogen (N 2) and oxygen (O 2), which make up more than 90% of Earth's atmosphere, do not absorb infrared photons. CO 2 molecules can vibrate in ways that simpler nitrogen and oxygen molecules cannot, which allows ...
