The type and efficiency of the light source is the largest contributor to the power consumed …
Basic Principle of NDIR Gas Detection Heimann Sensor
For CO2 detection there are two wavelengths of interest which are µm (here light red) and µm (here dark red). IR radiation with µm is not absorbed by either CO2 or other common gases in the atmosphere and is transmitted without loss to the detector. Therefore, it is well suited as reference with no absorption. IR radiation with µm wavelength is only absorbed by CO2 ...
