Optical Sensors. Optical (Infrared, or IR) sensors have also used for years to measure CO2 levels in the atmosphere or indoors. IR sensors use Infrared light that is passed through a sample of air in a small tube with inlet and outlet ports. CO2 molecules absorb the IR light of the same wavelength that is characteristic of the gas. The difference between the amount of light radiated by the IR ...

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. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR ...

The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.
Unlike electrochemical sensors, optical IR gas sensors detect the presence and concentration of these specific gas molecules and do not rely on chemical reactions. This results in improved longevity as they do not suffer from performance degradation over time. Non-dispersive infrared (NDIR) sensors are relatively simple optical devices consisting of an IR source, a gas sample, and a detector ...
