CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use nondispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts.

Carbon dioxide (CO ) measurement using NonDispersive ...

Capnography is a good example for NDIR spectroscopy, where the CO2 concentration in the exhaled breath of a person is monitored over expired volume or time. By evaluating the five characteristics of a capnogram, , frequency, rhythm, height, baseline and shape, deductions about the health of the patient can be drawn. For this purpose, both a fast measurement rate and a high sensitivity of the …

Measuring Carbon Dioxide (CO ) Using NonDispersive ...

Measuring Carbon Dioxide (CO2) Using NonDispersive Infared (NDIR) Technology NDIR sensors work using spectroscopy, which pertains to the dispersion of light into its component colors or energies. An example of this is light in the Visible Spectrum (the light humans can see), which is made up of a wide range of wavelengths (~390nm700nm).

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.

So if you want a good sensor go for this or other NDIR variants and don''t settle for cheaper ones that don''t directly measure CO2 level. I''ve bought more of these sensors by now, it''s excellent. What makes this sensor excellent that it measures directly the CO2 level unlike the ones that guess it based on air quality (cheaper ones _guess_ CO2 level based on various particle levels).
