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 ...

CO2 sensors - VENTS-US

The relay output is used to turn the fan on/off depending on indoor CO 2-concentration and the analogue output is used for smooth fan speed control for a fan with EC-motor or a fan with extra speed controller with 0-10 V input. In case of smooth fan speed control, the fan speed varies proportionally to carbon dioxide emissions. The relay and analogue outputs make the sensor compatible with any ...

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

among electrochemical sensors. Cross-sensitivities are limited as much as possible by MSA sensor design and filters; however, some key interactions still occur. CO sensors do have some inherent characteristics in terms of saturation, cross-sensitivity and cross-interference that may affect sensor performance. A typical electrochemical gas sensor contains three electrodes: the sensing electrode ...

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 ...
