Efficient gas sensor was made with zinc oxide nanoparticles synthesized by mechanical alloying using high energy planetary ball mill. As received and milled zinc oxide nanoparticles were characterized with X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and UV-Vis Spectroscopy techniques. Morphological study was carried out by using Transmission Electron Microscopy (TEM). The particle size of ZnO nanoparticles was reduced from micron to nano meter range after milling for 45h. The Ammonia gas sensing response of as received and milled ZnO nanoparticles was studied from I-V characteristics plots obtained for different concentration of ammonia (50 to 600 ppm). The sensitivity of zinc oxide was observed to increase with decrease in particle size from micron to nanometer.
