The FS01601 NH3 sensor is based on a fuel cell-type electrochemical principle. Its working electrode and counter electrode undergo reduction reactions, resulting in the release of charges and the formation of a current. The magnitude of this current is directly proportional to the concentration of ammonia, following Faraday's law. By measuring the current, the concentration of ammonia can be accurately determined.
