Para qué sirve un medidor de CO2 〖Actual 2021〗

Un medidor de CO2 sirve para medir la concentración de Dióxido Carbono, CO2, en el aire que respiramos. Si esa concentración es alta el medidor nos avisa de que el aire que respiramos ya ha sido respirado por otras personas. Y, por tanto, sirve para indicarnos si el grado de renovación del aire en espacios cerrados con aire del exterior es insuficiente.


Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive 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.
