Why NDIR? | Senseair

A n ondispersive infrared (NDIR) sensor has a detector that measures how much infrared light of a specific wavelength is absorbed by the surrounding air. This measurement is then used to calculate the concentration of a specific gas. › Compared to electrochemical sensors, the lifespan of the NDIR sensor is lengthy. This is mostly because these sensors have no sensor burnout, nor any sensor ...

CO2 measurement with NDIR co2 sensors

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 …


How does an NDIR CO2 Sensor Work? |

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 ...


Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
