The purpose of this study is the selection of an appropriate measurement technique for the detection of CO in indoor environments (100 ppm CO detection threshold limit), also in presence of high concentrations of ethanol (up to 1000 ppm) by using only one sensor. SnO2 sensors are widely used for the detection of air contaminants such as CO. Nevertheless, their application encounters some problems, first of all the effect of interfering gases. The low selectivity is in fact a well-known problem of these sensors. Moreover, the high operating temperature of metal oxide sensors implies in general high power consumption. This work aims at developing very low size and power consumption equipment, that could be battery operated, to be used in portable CO detectors. (c) 2004 Elsevier B.V. All rights reserved.
