MST141 electrochemical hydrogen sensor is a fuel cell-type sensor. Hydrogen and oxygen undergo corresponding redox reactions at the working electrode and counter electrode, releasing electric charges to form a current. The magnitude of the generated current is proportional to the hydrogen concentration and follows Faraday's Law. The level of hydrogen concentration can be determined by measuring the magnitude of the current.
