This paper presents the recent advances of ZnO Nanowires Based Sensors Devices. ZnO, an n-type, direct metal oxide semiconductor with a broad band gap, is projected to be the next generation functional nanomaterial for a wide range of sensing applications. Due to their exceptional optoelectronic, physicochemical, and electrical properties, such as low dielectric constant, abundant Zn-O bonds, high luminous transmittance, good physicochemical stability, enormous excitation binding energy, non-toxicity, biocompatibility, large surface area to volume ratio, and others, ZnO and its composites have opened a new era in the fabrication of sensors. The uses of ZnO nanostructures in the fields of environmental monitoring, biomedicine, and optical sensing are outlined in this thorough overview. To gain a better understanding of the function of ZnO in each of these sensors, fundamental sensing mechanisms of ZnO based sensors are explored. Limitations of the current methodologies and the forecast for the future have also been discussed.
