The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.
The advent of the 80's has seen the introduction of another important automobile innovation - the oxygen sensor. This gadget forms part of a vehicle's emissions control system and is also responsible for feeding data to the engine management computer. It does this by checking the exhaust hundreds of times per minute. In a nutshell, the car oxygen sensor helps maintain optimum engine performance and lower a vehicle's smoke emissions. The oxygen sensor is strategically located in the exhaust pipe. As such, it can easily detect the presence of rich and lean mixtures.
