Abstract

According to an embodiment, an information processing device includes a data obtaining unit and a data storage controller. The data obtaining unit is configured to obtain data measured by a sensor. The data storage controller is configured to store the data obtained by the data obtaining unit in a first memory of volatile nature when a sampling interval indicating an interval at which the data obtaining unit obtains the data is equal to or smaller than a threshold value. The data storage controller is configured to store the data obtained by the data obtaining unit and the data stored in the first memory in a second memory of nonvolatile nature when the sampling interval exceeds the threshold value.
