DATA LOGGER AND COMPUTER-READABLE STORAGE MEDIUM APPLIED TO THE DATA LOGGER

摘要

According to one embodiment, a data logger driven by a battery, includes a sensor, a log creation module, a detection module, a communication module, and a controller. The sensor measures a predetermined physical quantity. The log creation module creates a log based on the predetermined physical quantity. The detection module detects a take-over state that another data logger takes over creation of the log. The communication module communicates with said another data logger synchronized with the data logger. The controller performs a process to cause said another data logger to take over the creation of the log by communicating with said another data logger by the communication module when the take-over state is detected by the detection module.
