CO Sensor
FS01301 is a fuel cell electrochemical sensor. A reduction reaction occurs on the working electrode and the counter electrode and the charge is released to form a current. The magnitude of the generated current is proportional to the concentration of carbon monoxide and follows Faraday's law. Carbon monoxide can be determined by testing the magnitude of the current level of concentration.
