Abstract
A radio tag sensor system includes a plurality of radio tag sensor chips, which incorporate respective sensors, store unique identification numbers, a plurality of micro base stations, and a central processing unit which perform communications with the micro base stations via a connection network. Each of the micro base stations performs wireless communications with and wirelessly supplies electric power to only those of the radio tag sensor chips which are disposed in an assigned region thereof. Each of the assigned regions includes at least one radio tag sensor chip which is not included in the other assigned regions. The central processing unit controls the communications via the connection network. The central processing unit collects the sensed values from sensors of the radio tag sensor chips through the micro base stations, generates a spatial distribution map of the sensed values, and updates the spatial distribution map with time.
