Abstract

An electronic nose is a device designed to sense, classify, and recognize a product based on its aroma. The electronic nose is generally designed from four main parts, namely: sample handling and delivery system, detector system, signal conditioning and preprocessing, and pattern recognition software. The detector part plays an important role in determining the performance of the electronic nose. To speed up testing, the sample handling and delivery system can be designed by implementing multiple chambers assembled in one unit. However, the sampling rate is highly dependent on the characteristics of the detector system used. This study aims to determine the characteristics of the detector system on the speed of sample presentation by the sample handling and delivery system. The detector system is designed from eight of semiconductor sensors arranged in a row. The samples placed in the sample room are presented alternately with varying durations. Sensor responses recorded during the sample presentation were then analyzed. The sensor response results obtained for each sensor on the average of the three measurements are negative, so it can be concluded that in the re-flushing process, both sensors have recovered and are ready to be used for the second data collection. The value of the sensor response change in the flushing process is high enough so that the purging time can be reduced to shorten the sensor cleaning time from exposure to the sample aroma. The characteristics of detection system on the speed of sample presentation with the sampling period of 480 seconds can recover the response of the semiconductor gas sensor based on the results of ∆P, which is added with ∆F.
