PROBLEM TO BE SOLVED: To extend the battery life of a sensor terminal and to make the configuration of the sensor terminal simple.SOLUTION: A sensor network (1) comprises a sensor terminal (2#n) configured to detect measurement data of a measurement target every fixed time and transmit the measurement data by radio; an access point (3) configured to receive measurement data from the sensor terminal (2#n) by radio; and a server (4) configured to receive measurement data via the access point (3), calculate, from the reception time of the measurement data received first after the start of data collection and from a reference time nearest to the reception time, a correction time for the reception time, and store measurement data on the basis of the reception time corrected using the correction time. |
