Almost two decades after the publication of the first Iranian research report on gas sensors, no such device is commercially fabricated inside the country. Valuable experimental and theoretical articles and theses have been produced in Iranian universities and research organizations during this period, but recent liteature does not seem to set or cater to any specific industrial goal. In this paper, the commercially available gas sensors are introduced, their prominent quality factors described, and their present-day domestic and industrial applications specified. The intricate combinations of quality factors demanded by future applications are discussed, demonstrating that the available sensors are far fro satisfactory for even today’s requirements. It is established that, owing to the continuous research carried out on the subject, the fabrication technologies and know how related to major gas sensor types are within the national capacity the main barrier is connected to the internal market management.

Keywords: Artificial olfaction, Gas sensor, Applications, Industrial fabrication, Market demand, Local concerns.
