The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measures the absorption of the characteristic wavelength of light. NDIR sensors are most often used for measuring carbon dioxide.The best of these have sensitivities of 20â50 PPM.he gas is pumped or diffuses into the light tube, and the electronics measures the absorption of the characteristic wavelength of light.
