摘要

WO3 doped with NiO nanopowders with different NiO concentrations were prepared by sol-gel technique. The fabrication of the thin films for gas sensors applications was utilized using thermal vacuum evaporation technique. The morphological structure, crystallinity and optical properties of WO3 and NiO-doped WO3 nanopowders were characterized using scanning electron microscopy, X-ray diffraction and UV-Vis spectrophotometer, respectively. The electrical behaviors of the sensors were determined and measured by the two platinum electrodes sensor's resistance with different gases at various temperatures. The results show that a great response to CO2 gas was 164% at 5% doping ratio which is applicable for all environmental and industrial fields. GSM module by MAX circuit was applied on gas sensor devices to send a wireless message telling that there is a leakage in the area which the sensor installed.
