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 ...
It is largely used for carbon dioxide and hydrocarbon (HC) detection due to its reliability and simplicity of use. The applications using NDIR include: the automotive to measure gas emissions, industrial to detect gas leakage but also consumer to control air quality. NDIR can also be found in medical domain to monitor patients during surgical intervention. This application note deals with the ...
Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the ...
The detector consists of two independent channels with narrow band filters and a thermopile behind in one TO-39 package. The reference channel is equipped with a filter that has µm center wavelength (CWL) and the CO2 sensing channel has a filter with µm CWL.

Knowledgebase. NDIR Principle. Non-Dispersive Infra-Red (NDIR) detectors are the industry standard method of measuring the concentration of carbon oxides (CO & CO2). Each constituent gas in a sample will absorb some infra red at a particular frequency. By shining an infra-red beam through a sample cell (containing CO or CO2), and measuring the ...
