Abstract The analysis of proton conductivity in materials have great significance in humidity and ammonia sensors. In this manuscript, we emphasized on the ionization, adsorption, desorption and migration process of the conducting media in metal–oxide framework to propose the effective water and ammonia detection. In metal–oxide framework, tin (II) oxide (SnO) is used as a proton conducting material. The micro sheets of SnO were synthesized by hydrothermal alkaline solution technique at pH 12 and temperature (95 ℃). The film of SnO micro sheets was fabricated over the interdigitated electrodes and investigated under the different proton conducting media. Both water and ammonia form acid base system which is helpful in proton transfer. Herein, the synthesized material was characterized by powder X–ray diffraction (XRD), scanning electron microscopy (SEM), and high resolution transmission electron microscopy (HRTEM) for the phase and morphology. This work underlines that the SnO micro sheets behave as a good proton conducting material in metal–oxide framework.
