A carbon monoxide (CO) detector is a device that detects the presence of CO gases in order to prevent carbon monoxide poisoning. CO is a colorless, tasteless and odorless compound produced by an incomplete combustion of carbon-containing materials. It is often referred to as the "silent killer" because it is virtually undetectable by humans without using detection technology. Elevated levels of CO can be dangerous to humans, depending on the amount of gas that is present and the length of exposure. Smaller concentrations can be harmful over longer periods of time, while increasing concentrations require diminishing exposure times to be harmful.
The sensor used for this design is based on an electrochemical function, as this is a type of fuel cell that is designed to produce a signal current that is precisely related to the amount of the target gas (in this case, CO) in the atmosphere.
The CO detector will measure CO levels over time and sound an alarm before dangerous levels of CO accumulate in an environment.
