Multichannel data acquisitions of plural gas sensors and their precision management.

Abstract

Automated odor-sensing system based on plural semiconductor gas sensors and computerized pattern recognition techniques has been developed. Odor signals are detected by using eight TGS sensors which have different sensing properties for gases. But, there are control points of interest such as the signal acquisitions, the air steady level and heater voltages of TGS Sensors. These problems have been solved by the use of air brush and computerized techniques. © 1988, The Japan Society for Analytical Chemistry. All rights reserved.
