Abstract	In this work, the fabrication and gas sensing properties of tungsten trioxide (WO3) thin film gas sensors prepared by the spin coating method are reported. WO3 thin films were successfully deposited on glass substrates at 2000 rpm for 60 s, using spin coating method. The fabricated films were tested for their sensing performance towards various gases, including NH3, H2S, LPG, ethanol, and methanol. Among these, the WO3 thin films exhibited the highest gas response (68.51%) to H2S at an operating temperature of 120 °C with a concentration of 1000 ppm. The sensor also demonstrated good selectivity along with fast response and recovery times, highlighting the potential of spin-coated WO3 thin films for efficient and reliable for H2S gas sensing applications.
