Signal conditioning for electrochemical sensors

The gases most frequently monitored by handheld safety detectors which use electrochemical sensors are oxygen (O. 2), carbon monoxide (CO), hydrogen sulfide (H2S) and nitrogen dioxide (NO2). However, many other gases can also be monitored with electrochemical sensors. Electrochemical sensors are widely used in the medical sector.

How Does an Electrochemical Carbon Monoxide …

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.
