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 ...

Create Your Own CO Detector - Digi-Key

There are two basic types of electrochemical gas sensors, 2-electrode and 3-electrode. They both operate with the same basic principles. A gas diffuses into the sensor and makes its way to the working electrode. There it reacts with a catalyst and creates ions (charged molecules). Those ions move through the electrolyte (sometimes similar to battery acid) and again react at the counter ...

How electrochemical CO sensors detect gas. Gas that enters the sensor undergoes an electrochemical reaction that causes a change in the electrical output of the sensor. The difference in the electrical output is proportional to the amount of gas present. Gas enters the sensor through an external diffusion barrier that is porous to gas but nonporous to liquid. An internal organic vapor filter ...
