Non-Dispersive Infra-Red (NDIR) Sensors – Theory of Operation
NDIR gas sensors work by detecting the amount of light that is absorbed by the target gas. Gases absorb light energy at different wavelengths, depending on the chemical bonds in the gas.
This latest whitepaper from Gas Sensing explores different sensor measurement methods, how the Beer-Lambert Law is derived, and how it can be used to implement a real-world sensor.
Gas Sensing Solutions the specialists in CO2 sensing. GSS its in-house engineering and technical teams have many years’ experience in solid-state carbon dioxide gas sensor development.
