| Abstract | A sensor device includes: a sensor element configured to detect a physical quantity in a time-series manner; a data processing part configured to perform filtering on time-series data detected during a predetermined period by the sensor element to extract time-series data having a predetermined frequency component, and compare the extracted time-series data with a predetermined threshold value to determine one or a plurality of significant sections within the predetermined period, the extracted time-series data exceeding the threshold value in each of the significant sections; and a communication part configured to arrange and wirelessly transmit time-series data of each of the significant sections among the time-series data detected during the predetermined period by the sensor element. |
