In this paper, an intelligent electronic nose (EN)system designed using cheap metal oxide gas sensors (MOGS) is designed to detect fires at an early stage. The time series signals obtained from the same source of fire are highly correlated, and different sources of fire exhibit unique patterns in the time series data. Therefore, the error back propagation (BP) method can be effectively used for the...
In order to develop the technology for measuring and accumulating individuals' behaviors in a daily life, we designed and constructed an intelligent house. In this house, 167 sensors made from 15 kinds are installed. By using these sensors, we can acquire personal information such as location, posture and individual identification of home appliances and environment in the house. When we examined sensors'...
