electrochemical co sensor with relay

Operating principle ‐Electrochemical-type gas sensor

Figaro Electrochemical-type gas sensor are amperometric fuel cells with two electrodes. The basic components of two electrode gas sensors are a working (sensing) electrode, a counter electrode, and an ion conductor in between them. When toxic gas such as carbon monoxide (CO) comes in contact with the working electrode, oxidation of CO gas will occur on the working electrode through chemical ...
