VvUrtAfX CUIJiC OKTO^kCTKONjCS CO^L.TD. 'Working principle ❖ C02 gas is composed of different types of atoms have absorption spectrum in infrared range. Absorption intensity abides by Lamber-Beer's Law. Basic working principle of NDIR sensor is as below, VvUrtAfX CUIJiC OKTO^kCTKONjCS CO^L.TD. Basic mathematical model: A majority of both organic and inorganic polyatomic gas have specific absorptive wavelength in infrared region. It observes Lambert-Beer Law formula I = I0e-kpl when infrared light is coming through.
