What Does a CO2 Sensor Actually Do? | GDS Corp

06/11/2020· Working Principle CO2 sensors use the same operating principle as infrared hydrocarbon detectors. They create a beam of infrared light tuned to a specific frequency that is readily absorbed by CO2 molecules. The primary difference between an infrared CO2 detector and an infrared hydrocarbon detector is the choice of filter and infrared wavelength.

Oxygen sensor - Wikipedia

The sensors only work effectively when heated to approximately 316 °C ... The basic principle is that there is a cathode and an anode submersed in an electrolyte. Oxygen enters the sensor through a permeable membrane by diffusion and is reduced at the cathode, creating a measurable electric current. There is a linear relationship between the oxygen concentration and the electric current. With a two …

Operating principle ‐Electrochemical-type gas sensor

The basic components of two electrode gas sensors are a working (sensing) electrode, a counter electrode, and an ion conductor in between them. When toxic gas such as carbon monoxide (CO) comes in contact with the working electrode, oxidation of CO gas will occur on the working electrode through chemical reaction with water molecules in the air (see Equation 1).
