IR CO2 برای IAQ

How does an NDIR CO2 Sensor Work? | …

As the IR light passes through the length of the tube, the CO2 gas molecules absorb the specific band of IR light while letting other wavelengths of light pass through. At the detector end, the remaining light hits an optical filter that absorbs every wavelength of light except the wavelength absorbed by CO2 molecules in the air sample tube. Finally, an IR detector reads the remaining amount of light that was not absorbed by the CO2 …

CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon dioxide sensors only measure CO2.
