Abstract
A method of storing sensor data in a sensor tag is provided. The method comprises receiving new sensor data output from a sensor, comparing the received new sensor data with immediately previous sensor data to determine whether the comparison result satisfies a predetermined criterion, and storing the new sensor data in a tag memory when it is determined that the criterion is satisfied. Accordingly, efficient use of the tag memory is possible.
