The Application of Selected Saturated Standard Solutions to Examine the Uncertainty of Integrated Humidity Sensors Testing

Przemysław Otomański

Abstract

Results of experiments concerning humidity measurements have been presented in the paper. Integrated humidity sensors were used for the experiments, which transformed the value measured into a corresponding capacity. The structure of a measuring system was described, and the requirements concerning particular elements of the measuring track were defined. Using the regression method, an analytical equation was modelled, combining the output capacity value of the sensor with the examined humidity changes. With the use of the experimental results as well as the least square method, the values for the above equation’s parameters were determined.
