Fecha de publicación: 28/09/2017 Fuente: Wipo "Sensorization" A sensor device and a sensor management device are provided. The sensor management device transmits a change-of-use signal to the sensor device in a case where a use of the sensor device is changed, and the sensor device acquires data based on the change-of-use signal. Preferably, the sensor management device acquires a processing request for instructing the use of the sensor device, and automatically generates the change-of-use signal based on the processing request.
