Development of malodor monitoring system based on electronic nose technology

Odor can affect human health both directly and indirectly specifically malodor. In this work, the portable electronic nose is developed for environmental experiment and it can clearly classify characteristic of each odor source in the factory. Using a zero-grade air as a reference gas and reforming mechanisms of sample testing electronic nose can improve accuracy and efficacy including reduce time of experiment for environmental application. Therefore, this electronic nose can be used for finding the source of malodor that disturb the surrounding villager. The environmental electronic nose can apply to be the internet of things (IoT) device for remotely monitor the odor around the factory and in the village in the future.
