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 ...

Signal conditioning for electrochemical sensors

Signal conditioning for electrochemical sensors Pierre Sennequier Introduction . Unmonitored gas can rapidly become a danger. Consequently, in many industries such as refining, mining, and semiconductor industries, monitoring air quality is mandatory for security reasons. Gas monitoring is also important in parking lots and in connection with domestic use. For example, thousands of people are ...

Introduction To Electrochemical Sensors - Chemistry LibreTexts

· ELECTROCHEMICAL SENSORS. Electrochemical sensors are made up of three essential components: a receptor that binds the sample, the sample or analyte, and a transducer to convert the reaction into a measurable electrical signal. In the case of electrochemical sensors, the electrode acts as the transducer. 6 Figure 1: Schematic illustrating the basic components of an electrochemical sensor.

· A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some manner to gasses other than the target gas. This is called “cross-sensitivity” and is a result of the interfering gas also reacting on the sensor electrode. In some cases ...
