2. Exhaust gas analyzer - Wikipedia

   en.wikipedia.org/wiki/Exhaust_gas_analyzer

   The carbon monoxide concentration in exhaust gases is closely related, and almost proportional to the air fuel ratio in the rich regions. It is, therefore, of great value when tuning an engine. Carbon dioxide emitted is theoretically directly proportional to the fuel consumed at a given and constant air fuel ratio.

   The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measure the absorption of the characteristic wavelength of light. NDIR sensors are most often used for measuring carbon dioxide.

4. Carbon monoxide detector - Wikipedia

   en.wikipedia.org/wiki/Carbon_monoxide_detector

   A Kidde plug-in carbon monoxide detector. A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. In the late 1990s, Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm.

   Sensors for carbon dioxide are an example of this approach and they have been commercially available for several years. Cross-sensitivity of electronic chemical sensors may also be utilized to design chemical sensor arrays , which utilize a variety of specific sensors that are cross-reactive for fingerprint detection of target gases in complex ...
