Enrichment-layer Based Miniaturized Non-dispersive ...

· Currently, commercially available CO2 gas sensors are divided into two mains categories: non-dispersive infrared technique (NDIR) [2] and chemical techniques like resistive CO2 sensors [3]. NDIR sensors function by monitoring CO2 IR-absorption radiation at the specific wavelength of μm [2]. Only CO2 absorbs strongly at this wavelength implying high selectivity. However, miniaturization ...

Non-Dispersive Infrared (NDIR) Carbon Dioxide Sensors ...

· NDIR CO2 Sensor. Non-dispersive infrared, often called NDIR, sensors deliver high accuracy and fast response time. NDIR sensors have no contact with the gas, making them more reliable, and are constructed for specific gases so that they are unaffected by other gases. NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared …

Technical Note 169 Theory And Operation Of NDIR Sensors

The MultiRAE IR monitor uses an NDIR (non-dispersive infrared . absorbance) sensor to monitor CO. 2. Most molecules can absorb infrared light, causing them to bend, stretch or twist. The amount of IR light absorbed is proportional to the concentration. The energy of the photons is not enough to cause ionization, and thus the detection principle is very different from that of a photoionization ...
