The DSD03-M1K-JH15D is an exceptionally unique long-life electrochemical carbon monoxide (CO) sensor developed and manufactured by Daohe Shun. It is a fuel cell-type sensor where carbon monoxide and oxygen undergo respective oxidation-reduction reactions on the working electrode and counter electrode, releasing charge to generate current. The magnitude of the generated current is directly proportional to the concentration of carbon monoxide and follows Faraday's law. By measuring the current, the level of carbon monoxide concentration can be determined. The sensor output current level can be controlled by regulating the intake volume.
