초록

In this study, odor sensors were evaluated in two areas, which were reproducibility of measurements and linearity and correlation of results. The evaluation of linearity and correlation showed that the linearity of the measurement object substance at low, medium and high concentrations of all intervals, and correlation (R2) also appeared to be quite high, at 0.8 to 0.9. Specific performance evaluation results of ammonia, hydrogen sulfide, TVOC and complex odor sensor to the individual substances are somewhat different, but the result have able tendencies. All odor sensors showed detectable in all metrics at 5 ppb concentration in temperature 25oC, humidity 50%. However, there is needs to be determined that in many cases the standard deviation is 10% or more in 5 ppb, and reproducibility appears in the high concentration region with a standard deviation of less than 10%. Because complex odor sensor (MOS sensor) output value is relatively accurate concentration value for the odor and the reaction was stable, MOS sensor is to be considered methods for measuring the complex odor. Reactivity of ammonia, hydrogen sulfide and TVOC odor sensor to the concentration of individual odor substances stably displayed, but the reactivity of the mixture material showed the same trend, however, the hydrogen sulfide and TVOC sensor reactivity were unstable. There is thus a need to maintain the proper temperature and humidity environmental operating condition of odor sensors.
