- 摘要：
PROBLEM TO BE SOLVED: To record event information without obstructing sensing processing.
SOLUTION: In a sensor node, data are collected by a sensor, and an event is detected to record the event information. The data are periodically collected from the sensor, the collected data are stored in a first storing part, and when the event is detected, the event information is stored in a second storing part. When the data are collected from the sensor during the time elapsed from when the event is detected until the event information is stored, the processing of storing the event information is suspended, and after the data collected by the sensor are stored in the first storing part, the processing of storing the event information is restarted.
