  • 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.

  • Why NDIR? | Senseair

    A non-dispersive infrared (NDIR) sensor has a detector that measures how much infrared light of a specific wavelength is absorbed by the surrounding air. This measurement is then used to calculate the concentration of a specific gas. Compared to electrochemical sensors, the lifespan of the NDIR sensor is lengthy.

    The NDIR system needs a broadband IR source. This source can be steady state for thermopiles, but needs to be pulsed for pyroelectric and lead selenide detectors. The target gas will absorb more IR energy as the gas concentration increases. This means that as the gas concentration increases the signal from the detector will decrease. Concentrations from % down to ppm can be measured using NDIR.

  • 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.

    The Functional Principle of Smartgas Sensors & ModulesGas Sensors For The Process Measuring TechnologyGas Sensors For Ambient Air MonitoringThe IR principle uses the individual absorption spectrum of the gas being measured. The exact gas concentration is determined through precise quantitative analysis of this spectrum. Because of this, their gas sensors function very selectively and are virtually unaffected by other environmental factors or gases. The functional principle of our gas sensors: long-term stability and performance thanks to NDIR technology from smartGAS As all measured gases absorb in varying spectral ranges, a kind of “fingerprint” arises that allows very selective characterization without cross-sensitivities. Gas sensors from smartGAS possess an integrated electronic evaluation system that displays a simple to use concentration signal to you as the user and reliably compensates for all drift and temperature influences.
