The NDIR CO2 Sensor Implementation and Temperature ...

And it could be used for fire detection, cultivation under structure, and so on. Under these circumstances, CO2 monitoring has used NDIR(Non-dispersive Infrared) gas sensors and contact type gas sensors such as semiconductor and solid electrolyte. The contact type gas sensors have the merit of low power and small size, but their short lifetime, poor gas selectivity and temperature dependence ...

Operating principle ‐NDIR-type gas sensor

NDIR gas sensor consist of an infrared source, detector, optical filter, gas cell, and electronics for signal processing. A single light source, dual wavelength type gas sensor has two detectors and two optical filters of different wavelengths which are placed in front of each detector. Infrared light that is absorbed by a target gas passes through the active filter with a particular bandwidth ...

NDIR Gas Sensors - Electrical Optical Components, Inc.

An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not pre-filtered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using ...

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.
