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.

What is NDIR? | Oshino Lamps Ltd.

NDIR stands for ''Non Dispersive InfraRed'' and it is s gas concentration measurement method that uses the unique absorption wavelength range of each gas. For example, CO2 absorbs infrared wavelength region of µm. Since amount of infrared which passes through the atmosphere depends on concentration of CO2 gas contained therein, it is ...

NonDispersive Infrared, NDIR, Carbon Dioxide Sensors ...

A basic NDIR sensor consists of an infrared light source, a sample chamber, an infrared filter, and infrared detector. For carbon dioxide sensing, room or duct air is allowed to flow in and out of the sample chamber. Infrared light waves are created by the source and sent through the sample chamber to the detector. As the infrared light passes through the air in the chamber, light of a ...
