Oxygen Sensor
FS01501 is a type of fuel cell electrochemical sensor. The working electrode and counter electrode undergo a reduction reaction and release charge to form a current. The magnitude of the current generated is proportional to the concentration of oxygen and follows Faraday's law. By measuring the magnitude of the current, the level of oxygen concentration can be determined.
