How does an NDIR CO2 Sensor Work? |

January 05, 2021 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.

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 the two detectors.

How to calibrate a CO2 sensor? - Yoctopuce

2015-05-01· Most serious CO2 sensors are based on the NDIR (non-dispersive infrared) technology, consisting in measuring the number of CO2 molecules between a particular infrared light source and a detector. At the factory, the sensor manufacturer must perform a full sensor calibration with different CO2 concentrations to ensure a correspondence between the detector measures and the actual levels of CO2 ...

2016-11-29· In the case of NDIR, the distance between the detector and emitter (which determines the concentration range the sensor can detect) is often the component that dictates the dimensions of the sensor. Fortunately, for CO 2 breath analysis, the level of CO 2 is in the range of 4–5%, thus the CO 2 concentration can be measured with relative short paths lengths.

Optical Filters for Sensors and Detectors - Iridian ...

Unlike most photonic sensor technologies such as NDIR which employ both optical illumination and detection, in photo-acoustic spectroscopy (PAS) light is converted into sound by the sample gas. Gas in a sample chamber is excited by modulated MWIR light. Absorption of this light energy results in an increase in temperature and pressure of the gas under interrogation which in turn results in ...
