ABSTRACT
Industrialization can be greatly appreciated only by limiting the downside of the proposed technology. In this aeon, the recurrent monitoring of industries is statutory in detecting harmful gases and explosions for the global environment safety. Hence, employing specific gas sensors for detecting malicious gases benefits the welfare of the society. Thus, in this present work, we developed an energy efficient toxic gas sensor using ZnO thin film by seed layer assisted hydrothermal technique. The sensing mechanism of ZnO with the CO analyte was explained and the sensing parameters such as sensitivity, selectivity, response and recovery time were studied. Further, the developed energy efficient sensor was embedded with wireless sensor assembly for online monitoring which may be functional in developing portable, compact and cost-effective system for various real time industrial control applications.
