Polyaniline (PANI) based Metal oxide nanocomposite thick films were prepared by using the screen printing technique. The films were fired and optimized temperature of 60ºc for 30 minutes in an air atmosphere. In the present work, Polyaniline is prepared by polymerization of aniline under acidic conditions. Zinc Oxide (ZnO) nanoparticles and Tin Oxide (SnO2) prepared by the Precipitation method at room temperature. The films were showing a decrease in resistance with an increase in temperature indicating semiconducting behavior. It is observed that PANI doped Metal oxide nanocomposite sensor shows a high response and sensitivity with good repeatability as compared to that of pure PANI and Metal oxide nanoparticle. The crystallinity and the crystallite size were examined by X-Ray Diffraction technique (XRD), and Scanning Electron Microscopy (SEM). Also confirms that the properties of pure polyaniline can be improved by the synthesis of Polyaniline - Metal oxide nanocomposites
