When infrared radiation interacts with gas molecules, infrared light is absorbed by the gas molecules at a particular
wavelength, causing vibration of the gas molecules. NDIR (Non-Dispersive Infrared) gas sensors detect a decrease in
transmitted infrared light which is in proportion to the gas concentration. This transmittance, the ratio of transmitted
