Improving the artificial odor and gas source localization system using the semiconductor gas sensor based on RF communication

Locating gas leaks, chemical hazard sources and smuggled narcotics are difficult tasks to be done by conventional systems, because they usually exploit human experts or dog trackers to search and solve the problems. An electronic system that can perform such tracking automatically, constantly and accurately is expected to replace these duties. This paper describes how an artificial system with such ability is realized. It can be used as a tool to conduct various applications, such as locating gas leaks and searching for chemical hazards.
