Nowadays, technologies for sensing the presence of gases are being extensively studied and explored for identification or recognition at room or any other temperature. Advanced sensor machinery for gas detection is used in various fields such as greenhouse gas monitoring, chemoresistive, and optical gas sensor, etc. Based on indigenous technical advances and literature investigations, new developments and improvements in sensors proposed to meet the increasing demand of rigorous performance in forthcoming varied applications, are described in the present study. This review paper provides descriptions, evaluation, comparison and evolutions in prevailing pioneering technologies for gas sensing. Various sensing technologies are given, based on the variation of electrical and other properties. Furthermore, this paper focuses on various metal oxides and electrical properties for performance indicators to compare different sensing technologies analyze the factors, temperature, or room temperature several corresponding improved approaches.
