The Theory Behind Carbon Monoxide Electrochemical Sensors ...

· Since electrochemical sensors work with the same theory but different materials, we have described only how the CO sensor works in this application note. 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 ...
