Description: 
In this paper, the development of a portable environmental monitoring system based on a gas sensor array is proposed. The most critical issues related to the microsensor, the interface circuit and the data analysis have been addressed. The complete system is designed to exhibit high precision and large dynamic range. Experimental results on a prototype, obtained by injecting ethanol on a microsensor coated with Pd-doped SnO2, have confirmed the theoretical expectations, demonstrating that the system is suitable for high-precision gas sensing applications.
