Inorganic materials play an important role in development of chemiresistive gas sensors. We have prepared tungsten oxide (WO3) by hydrothermal method at 150oC and it used for gas sensing applications. The prepared sensor film was characterized by X-ray diffraction (XRD), Raman Spectroscopy, X-ray photoelectron spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) and contact angle. Developed tungsten oxide (WO3) sensor film works excellently at 200oC operating temperature and shows higher response to NO2 gas. The chemiresistive metal oxide sensor is highly stable, reproducible and has short response and recovery time.
