Abstract

In this paper it is proposed a solution for the numerical linearisation of non-linear parameter dependent sensors. The sensor data-processing architecture combines non-linear analogue to digital conversion with intelligent data processing based on an artificial neural network both implemented using a microcontroller. An application of the processing architecture to gas and vapour concentration measurement is reported.
