Principle and introduction of formaldehyde sensor
2020-06-17
The sensor contains a conventional two electrode fuel cell sensor. The working electrode releases electrons to the counter electrode through the external circuit, and consumes with the reduction of oxygen at the end of the counting electrode. The internal circuit has the ion current in the electrolyte to achieve. It is one of the air quality sensors.
