  • 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.

  • Complete Gas Sensor Circuit Using Nondispersive Infrared (NDIR)

    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 concentration of the gas component can be determined.
