Awakening and sleeping are recognized as human behaviors by a gas-sensor output using a fuzzy reasoning. The gas sensor is made from a tin oxide and is sensitive for various gases. The sensor output has a daily periodical pattern. The pattern descends gradually during sleeping and ascends suddenly as of awakening. Recognition is performed using the characteristics of the pattern. At that time, the min-max compositional method is adopted. There are only six rules in this system.

Ethylene gas is a gas naturally released by fruits. The maturity level of these fruits could be predicted from the amount of ethylene around them. To maintain the freshness of these fruits, the concentrations of surrounding ethylene need to be monitored. Therefore, suitable gas sensor ethylene were still in progress to get good respond. In this paper systhesis of pure SnO2 nanoparticle from SnCl2.2H2O and water solution in precipitation method was held. The tin oxide powder was obtained in good distribution with nanoparticle size. This nanoparticle powder was formed into thick film, using ethylene glycol as solvant. To observe this sensor characteristics, several test was held in various conditions. Gas testing used pure ethylene gas show better respond at higher than room temperature but recovery time still unsatisfying.
