This paper proposes a search system and a query language for sensor database in room environment. The search system is required to have little dependency on sensor environment. Description of sensors and knowledge description written in RDF/OWL reduce dependency of search system on sensor environment. The features of the language are to manipulate sequential sensor data as time interval and its recursive structure. By utilizing these features, aggregation of life information in various granularities (ex. average of sleeping time for every week, frequency of watching TV when sitting and not sitting, and so on) is expressed intuitively. With Sensing Room, we built an actual system. Independency on sensor environment and expressiveness of the query language are discussed. Search time in practical usage is examined.
