The MQ-7 carbon monoxide sensor is especially designed to be sensitive to carbon monoxide (CO) gas which is emitted by vehicles, factories, etc. Since this gas is considered toxic to humans at certain levels, concentration of CO is used to determine the air pollution in a given area.
2020-01-18· The most important component of a carbon monoxide alarm is the sensor: this is the part of the device that actually detects the CO concentration in the room. There are basically three different types of sensors: electrochemical, metal-oxide, and colorimetric ones. They all detect CO in a different way, however, the trigger is always the same: elevated CO concentration in the air around the ...
2018-10-15· The carbon monoxide sensor consists of three electrodes immersed in a liquid electrolyte (a non-metalic liquid that conducts electricity, usually through acids or dissolved salts). The three electrodes are the working electrode, the reference electrode, and the counter electrode. The most important of these is the working electrode (WE). The working electrode is made of platinum, which is …

Carbon monoxide has a computed fractional bond order of , indicating that the "third" bond is important but constitutes somewhat less than a full bond. Thus, in valence bond terms, – C≡O + is the most important structure, while :C=O is non-octet, but has a neutral formal charge on each atom and represents the second most important resonance contributor.
