· The carbon monoxide sensor consists of three electrodes immersed in a liquid electrolyte (a non-metalic liquid that conducts electricity, usually through acids or dissolved salts). The three electrodes are the working electrode, the reference electrode, and the counter electrode. The most important of these is the working electrode (WE).
Electrochemical sensors use a gel to detect CO. Electrochemical sensors are mainly used to detect Oxygen and toxic gas. They measure a chemical reaction within the sensor that creates an electrical output proportional to the CO level. Essentially, EC sensors are small fuel cells composed of noble metal electrodes in an electrolyte.
