  • Nondispersive infrared sensor - Wikipedia

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

    Nov 29, 2016 · NDIR sensors operate on the principle of IR radiation being absorbed by a target gas. Utilisation of different absorption bands in the IR spectra allows the sensor to be specific to a desired gas. CO 2 strongly absorbs IR radiation at a wavelength of 4.3 μm, fortunately avoiding the water vapour absorption bands at 2.5–2.9 and 5.2–7.5 μm .
