This work presents an ongoing research aimed at interpreting the responses of non-selective gas sensors (such as metal oxide resistive ones) in terms of simple IF THEN rules. In particular, it is shown how a logical combination of the output of three extremely low-cost sensors, namely MQ131, MQ136 and TGS2602, can be arranged to produce IF THEN inferences able to discriminate among CO, SO2 and NH3 emissions. The outcome is quantitatively similar to that obtained with high-selective and costly chemical sensors. The experimental results, albeit grounding on an empirical base, seem to support the idea that smart compositions of low-cost sensors are able to manifest surprising discrimination abilities.

Abstract

This work presents an ongoing research aimed at interpreting the responses of non-selective gas sensors (such as metal oxide resistive ones) in terms of simple IF THEN rules. In particular, it is shown how a logical combination of the output of three extremely low-cost sensors, namely MQ131, MQ136 and TGS2602, can be arranged to produce IF THEN inferences able to discriminate among CO, SO2 and NH3 emissions. The outcome is quantitatively similar to that obtained with high-selective and costly chemical sensors. The experimental results, albeit grounding on an empirical base, seem to support the idea that smart compositions of low-cost sensors are able to manifest surprising discrimination abilities.
