1. A data collection system, comprising:
a plurality of data output apparatuses that are installed at places different from each other, and each output data in wireless communication; and
a data storage apparatus that stores the data output from the plurality of data output apparatuses, wherein
each of the plurality of data output apparatuses comprises
at least one sensor that generates the data, and
a wireless communication apparatus that transmits the data toward the data storage apparatus, and
the wireless communication apparatus
stores, for each of the plurality of other wireless communication apparatuses that can be a transmission destination of the data, connection information for connecting to the other wireless communication apparatus and priority information indicating a priority of the other wireless communication apparatus, and
repeats processing of reading the connection information, and performing communication by using the read connection information in descending order of the priority until the communication succeeds when a transmission route of the data is set,
wherein the data output apparatus adjusts a volume of the data to be transmitted in response to time since the data transmitted are output until the data transmitted reach the data storage apparatus, wherein the data output apparatus adjusts the volume of the data by adjusting a measurement time of the sensor when one piece of the data is generated.
