A thin film carbon monoxide (CO) gas sensor based on PEDOT:PSS/Fe (salen) has been developed using the spin coating technique on several glass pieces with interdigitated Au electrodes. The change in electrical resistance of the sensors with various content of dopants was measured in different CO gas concentrations and temperatures. It is found that Fe (salen) as a dopant can significantly improve the performance of PEDOT:PSS based gas sensors. Least square support vector regression (LSSVM) method was applied to predict the gas response characteristics of the films for different testing conditions. Modeling results show a satisfactory agreement with experimental findings.
