Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( 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.

On the use of CO2 sensors in schools and other indoor ...

Oct 29, 2020· Using models in support of and synergy with CO2 sensors could have merits. Always on. CO2 sensors measure continuously over time, without the need for any supervision. Other measures, such as outdoor teaching, achieve a similar result (minimizing aerosol-based transmission), but can only be deployed at selected times and not continuously.
