co sensor operation

Operating principle ‐Electrochemical-type gas sensor

The oxidation potential of CO gas (as expressed in Equation 1) is lower than the oxidation potential of the electrode(2H+ + 2e-⇔ H 2), oxidation of CO has less noble potential than deoxidization. Since this reaction occurs easily, no external energy is needed to stimulate the sensor’s chemical reaction, unlike with three-electrode type sensors. As a result, this two-electrode type ...

System-Connected Carbon Monoxide Detectors

Electrochemical CO Detector Operation Electrochemical sensors use a platinum electrode and acid combination to promote a reaction between CO and the oxygen in the air, which then produces an electric current. When CO is present in the air over time, if the current increases beyond specific thresholds, the alarm is sounded.

How Carbon Monoxide Detectors Work | HowStuffWorks

Before selecting a carbon monoxide (CO) detector, do a little research. Determine whether your local laws require you to have CO detectors of a particular type or configuration. You'll need to decide whether you'd rather have a battery-operated or plug-in detector. A plug-in unit goes into any wall outlet and can be moved to another room if necessary. But unless y­our plug-in unit has a ...

Capacitive sensing - Wikipedia

Projected capacitive touch (PCT) technology is a capacitive technology which allows more accurate and flexible operation, by etching the conductive layer. An X-Y grid is formed either by etching one layer to form a grid pattern of electrodes, or by etching two separate, parallel layers of conductive material with perpendicular lines or tracks to form the grid; comparable to the pixel grid ...
