Chemical production activities cause large amounts of ammonia to evaporate into the atmosphere, degrading air quality and even endangering public health, so monitoring in real time is significant. Traditional detection techniques, including spectrometers, chromatography, pumping methods, are characterized by high costs, complex operation, significant delays, limited compatibility, which obstructs immediate identification timely provision information. Due their distinct benefits such as compact size, affordability, quick response time, lack need for manual resistive sensors hold promise real-time tracking emissions chemical manufacturing processes. In recent years, utilizing metal-oxide semiconductor (MOS) nanomaterials have become a popular area research due sensitivity, strong stability, acceptable recovery times. However, interface circuits existing MOS gas mainly focus on sensor configuration data acquisition. These functions array timing control processing; cannot be realized directly them, reduces system integration increases application complexity. This paper begins examining key design strategies MOS-based aimed at enhancing sensing capabilities, offering researchers foundation work creating high-performance sensors. Based this, complete measuring programmable circuit an introduced, can integrate configuration, signal acquisition, processing, output recognition results. Finally, current challenges future opportunities systems presented. The purpose this review offer suggestions promote use these upcoming
