A management server 103 holds a parameter of a sensor device 101 and change management information related to a change in the parameter, and transmits the changed parameter and the change management information to the sensor device. The sensor device 101 holds the parameter and the change management information transmitted from the management server, and transmits the change management information to the management server together with measurement data. The management server collates the received change management information and preliminarily-held change management information to determine the change in the parameter on the basis of a result of the collation.

A method of controlling an electronic apparatus is provided. The method includes the steps of receiving measurement values for the state of air displayed on a plurality of external electronic apparatuses from each of the plurality of external apparatuses, calculating rates of change of the measurement values for each of the plurality of external electronic apparatuses based on the received measurement values, identifying external electronic apparatuses of which differences of the calculated rates of change belong to a predetermined range among the plurality of external electronic apparatuses, correcting the measurement values received from at least one external electronic apparatus among the identified external electronic apparatuses such that the measurement values received from the identified external electronic apparatuses become the same as one another, and transmitting information related to the corrected measurement values to the at least one external electronic apparatus.

This disclosure relates to systems and methods for management of information, including environmental information, obtained by a variety of sensors associated with one or more distributed mobile sensor platforms. In certain embodiments, the geographically transitory nature of a mobile sensor platform may be leveraged to facilitate collection of environmental information over a larger geographic area than that of a fixed sensor platform. Embodiments disclosed herein provide for information consistency and/or quality checking of information obtained by mobile sensor platforms. Further embodiments may be used to incentivize the collection and/or acquisition of certain data via point and/or credit-based compensation.
