SENSOR DEVICE AND METHOD EXECUTED BY SENSOR DEVICE

A sensor device 10 is attached to various products. The sensor device 10 includes a sensor unit 12, a communication unit 200, a storage unit 18, a power storage unit 24, and an energy harvesting unit 22. The sensor unit 12 measures a condition related to a product. The communication unit 200 outputs information based on the measurement result from the sensor unit 12. The storage unit 18 stores the measurement result from the sensor unit 12 and the information output from the communication unit 200. The power storage unit 24 supplies electric power for operating at least one of the sensor unit 12, the communication unit 200, and the storage unit 18. The energy harvesting unit 22 converts energy of an external environment into electric power and charges the power storage unit 24.
