Study of Perception of Odor in Human Compared to Gas Sensor in the Case of Ammonia

摘要

This paper works on the study of the perception of ammonia odor in human compared to the sensor response ofammonia gas sensor. The study aims to standardize the odor measurement. This work investigated various concentration levels ofammonia on the relationship between the response of gas sensor and the human odor perception in terms of annoyance and strengthof odor perceived. The results showed that both of the response of ammonia gas sensor and the human perception in terms of odorstrength increased accordingly to the concentration level of ammonia. The denser concentration of ammonia, the more sensorperceived odor strength as in human perception. There was, however, an inconsistent relationship of the response of ammoniasensor and the annoyance perception, which might be due to the emotions and complexity of individual human perception.
