ABSTRACT In this work we report the results of a one year long performance evaluation of a solid state multi-sensor device calibrated with on field data, operating in a quantitative city air pollution scenario. Univariate enose calibration in controlled environment typically hold
Noise and Repeatability of Odorant Gas Sensors in an E-Nose
free download
ABSTRACT The impact of the characteristics of the sensors used for electronic nose (e-nose) systems on the repeatability of the measurements is considered. The noise performance of the different types of sensors available for e-nose utilization is first examined. Following
