Carbon dioxide sensor - Wikipedia

A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes. Nondispersive Infrared (NDIR) CO 2 ...

CO2 measurement with NDIR co2 sensors

Measuring method. The E+E CO2 sensors feature the dual wavelength/dual detector NDIR principle. One detector is tuned to µm wavelengths, which is absorbed by CO2, the second detector on µm, which is not affected by any gas. For every single measurement the CO2 concentration is calculated from the outputs of the two detectors.
