Carbon Monoxide Sensor Detector Review | Engineers Edge ...

Jan 12, 2012· Electrochemical CO Sensors: This is a type of fuel cell that instead of being designed to produce power, is designed to produce a current that is precisely related to the amount of the target gas (in this case carbon monoxide) in the atmosphere. Measurement of the current gives a measure of the concentration of carbon monoxide in the atmosphere.
