The DSD03-M1K-JH50 is an exceptionally unique 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.
Features
