Abstract
The aim of the study was to evaluate whether it is possible to extract the information about the gas concentration despite the influence of humidity. Commercial semiconductor sensor response was examined under the application of a periodic temperature change. The data was collected using measurement protocol for different concentrations of ammonia at specified levels of relative humidity. In this work we focused on the evaluation of the Discrete Wavelet Transform analysis results obtained during experimental investigation of the single semiconductor gas sensor in the presence of humidified atmosphere containing ammonia. The results of the analysis show that proposed method enable the possibility of determine the low concentrations of ammonia.
