Abstract
A sensing system includes: a wireless sensor terminal that includes a sensor, a processor, and a memory; and a concentrator that includes a processor and a memory and is connected to the wireless sensor terminal. In the sensing system, the wireless sensor terminal includes a first signal processing unit that processes sensor data measured by the sensor, and a first wireless communication unit that transmits the data output by the first signal processing unit. The concentrator includes a second wireless communication unit that communicates with the first wireless communication unit, and a second signal processing unit that calculates a feature quantity based on the data received from the wireless sensor terminal, determines a principal component according to the feature quantity by a principal component analysis, and generates a principal component list corresponding to the principal component.
