Abstract [en]

The present work describes an algorithm to enhance selectivity of metal oxide

(MOX) gas sensors. The main objective is to improve gas discrimination

performance of MOX sensor using a temperature modulation combined with

phase space method. Our aim is to achieve a very good gas discrimination performance

based on a fragment of sensor signal, rather than using the response

of sensor for entire modulation signal.

The basic principle behind this thesis work is that investigating in sensor

response and extracting a segment with high class separability from a full modulation

cycle of sensor response. The fragment of sensor signal is obtained by

variable sliding window. A segment that gives more separable classes is taken

for discriminating between a set of given analytes. In this work we demonstrate

the developed algorithm with a single, commercially available MOX sensor, Figaro

TGS 2620, which is temperature modulated with a sinusoidal waveform.
