| Popis: | The purpose of this paper is to provide a kinetic model for the CO gas electrochemical sensor in which the gas sensor behavior is simulated over time. This simulation was done by writing and solving sensor-equivalent artificial equations. The model showed that the sensitivity of a sensor, as well as its catalytic property, is a function of the input pores diameter, the gas passing membranes thickness, and the volume of the sensor. Different sensors were made with membranes with different porosity and thicknesses, to verify the accuracy of the proposed model, and it was observed that the model had a good match with the test results. |
