When infrared radiation interacts with gas molecules, infrared light is absorbed by the gas molecules at a particular wavelength, causing vibration of the gas molecules. NDIR (Non-Dispersive Infrared) gas sensors detect decrease in transmitted infrared light which is in proportion to gas concentration. Non-dispersive infrared (NDIR) gas detection is a technique based on the theory of gas molecular absorption spectroscopy [1], [2]. The infrared light irradiating across the gas is absorbed explicitly in a specific spectral band due to the vibrations of the gas atoms [3], [4]. . and it was also the first online continuous process gas analyzer .
