We have created an electronic nose using the metal oxide sensors from two commercial brands, FIS and FIGARO1. In this paper, we use this electronic nose to classify the smell from 3 types of burning materials and then we apply the standard back propagation and recurrent back propagation neural networks to train and classify those burning smell. In the experiment, we test 3 kinds of joss stick, 2 brands of cigarette, and a mosquito coil. Moreover, we also measure the difference of concentration of smoke by varying the number of burning joss stick. The results show that it is able to classify the smoke correctly. The idea of this research would be able to apply for making a smart smoke detector in order to be able to detect a harmful burning material precisely before it is too late to stop the fire.
