Study of the interferences of No_2 and Co in solid state commercial sesnors

摘要

Commercial solid state gas sensors have been used to measure NO_2 and CO concentrations in the range of thr first alarm thresholds for urban environments. Their mutual interference has been studied at three operating temperature ranges. The results showed that different sensitivities and selectivities can be obtained with the same type of sensors. This fact is used to successfully train a neural neural network.
