Abstract

In this paper, we have presented the design and invention of an electronic nose (E-nose) that can work and analyze the results via a network system such as LAN or WiFi. The MWCNTs/polymer composites were used as a gas sensor array. The constant current circuit was newly designed for gas sensor measurement. The fabricated E-nose showed a high performance for indoor air monitoring with very low noise.
