Polypyrrole, Graphene oxide and WO₃ nanostructures are synthesized by chemical polymerization, Modified Hummers method and hydrothermal method respectively. PPy–GO–WO₃ hybrid nanocomposite is synthesized by the polymerization of polypyrrole in the presence of GO–WO₃ nanocomposite. Band gap energy of the hybrid nanocomposite is calculated as 4.1 eV using UV–Visible absorption spectroscopy. Electrodes are fabricated by spin coating the sensing materials on a Printed Circuit Board. The electrodes have been investigated for their response towards Oxygen, Hydrogen, Ammonia and Liquid Petroleum Gas at room temperature. Among the different gases, electrodes are selectively sensitive to ammonia gas with improved sensitivity (58%), response time (50 s) and recovery time (120 s) in the presence of 10 ppm gas. The lower limit of detection of the electrode is observed as 5 ppm. The reproducibility of the response of the electrodes is tested and it is stable for the period of 50 days.
