The optical, physical, biological, electrical, and optoelectronic features of perovskites make them fascinating materials. They are a viable contender for a variety of applications because of their unusual sensitivity, selectivity, and long-term stability. The various structures and their properties are explained in this chapter. It also explains the various sensing mechanism that are responsible for the adsorp-tion of various kinds of gas molecules. The significant potential for sensor applica-tions is suggested by their outstanding hydration-dehydration, electronic transition, adsorption-desorption, phase transition, and ion intercalation-declaration. In both solid and solution phases, several perovskite nanomaterial-based devices have been proven to offer exceptional sensing capabilities to diverse chemical and biological species. This chapter discusses the structure of perovskite, its synthesis, and the manufacture of useful sensors, as well as their applications in temperature, humidity, and gas sensing. Finally, using real-time demonstration, we outline the viewpoints and propose realistic directions for the future development of innovative perovskite nanostructure-based sensors.
