<P>PROBLEM TO BE SOLVED: To perform correction with suppressed power consumption concerning sensors arranged in multiple places. <P>SOLUTION: A sensor network system includes: multiple sensor parts arranged in multiple places; a sensor output transmission part for transmitting outputs from the respective sensor parts; and a correction device 30 for correcting outputs from the sensor parts. The correction device 30 includes: a sensor output collection part 33 for receiving respective sensor outputs from the sensor output transmission part; an environment parameter information collection part 34 for collecting environment parameter information related to respective environment conditions that give influence on the respective sensor outputs; an influence characteristic storage part 32 for storing the characteristics of change in the respective sensor outputs with respect to the change of previously acquired environment parameters; and a correction calculation part 31 for correcting the respective sensor outputs on the basis of the influence characteristics stored in the influence characteristic storage part 32 after associating the respective sensor outputs with the respective pieces of environment parameter information. <P>COPYRIGHT: (C)2013,JPO&INPIT |
