The DSD03-M1K-JH30 is a long-life electrochemical carbon monoxide sensor developed and manufactured by Dao He Shun. It is a fuel cell-type sensor, where carbon monoxide and oxygen undergo corresponding oxidation-reduction reactions on the working electrode and counter electrode, releasing charge to generate current. The magnitude of the current is directly proportional to the concentration of carbon monoxide, following Faraday's law. By measuring the current, the level of carbon monoxide concentration can be determined.
