| Outline of Final Research Achievements |
Smell distinguishable equipment was constructed by transient response of semiconductor gas sensor. Optimum waveform for heater voltage of the gas sensor to distinguish the kinds of alcoholic gases was explored by simulation with the transient response model constructed originally. It was found out that the 9th root waveform of heater voltage made the largest separations among the responses for four kinds of alcoholic gases. Equipment which distinguishes the four kinds of alcoholic gases automatically with PIC microprocessor by using the differences of the area, rise up and down part and gradient of the transient response was made. The equipment could distinguish the methanol, ethanol, n-propanol and n-butanol gases successfully.
