This paper describes an approach towards the development of a portable E-Nose device based on an array of Metal Oxide Semiconductor (MOS) sensors, for early on-site dry rot detection on building timbers. A dedicated real-time data acquisition system with a programmable voltage generator, self-calibration techniques and custom visual software programmes has been designed and constructed for this application. Experimental results show that this data acquisition system can accurately measure a large range of resistive sensor response and is suitable for measuring both conducting polymer and MOS sensors.
