  • Performance and Environmental Correction of a Low-Cost NDIR

    Jul 03, 2017 · Non-dispersive infrared (NDIR) sensors are a low-cost way to observe carbon dioxide concentrations in ambient air, but their specified accuracy and precision are not sufficient for some scientific applications. An initial evaluation of six SenseAir K30 carbon dioxide NDIR sensors in a lab setting showed that without any calibration or correction, the sensors have an individual error between approximately 5 to 21 parts per million (ppm) when compared to a Los Gatos Research greenhouse gas

  • 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.
