In this contribution we present an electronic system specially designed to perform conductometric measurements in chemical gas sensors based on individual nanowires operated in self-heated mode. Details about the precautions needed to be taken into account are thoroughly presented. The system is compact and low-power, it features autocalibration and auto-range capabilities and it is ready to be integrated in large networks of wireless sensors. It represents one of the first attempts to interface nanotechnology-based sensors with smart wireless technologies.
