Abstract
Provided is a data transfer device capable of avoiding reduction in a data communication speed of a sensor in an area with a low wireless communication line speed while suppressing occurrence of overflow. The data transfer device includes: a data acquisition unit that acquires sensor data detected by a sensor at a first data communication speed; a communication unit that transmits the acquired sensor data to an external server at a second data communication speed; an accumulation amount calculating unit that calculates a temporal transition of a predicted accumulation amount of the acquired sensor data in a memory using the first data communication speed and the second data communication speed; and a determination unit that determines whether or not the sensor data to be accumulated in the memory will overflow on the basis of the temporal transition of the predicted accumulation amount.
