1. A wireless sensor system comprising:
one or a plurality of wireless terminal devices each being driven by electric power stored in a power storage unit, and being configured to transmit measurement information indicating a result of measurement by a sensor;
a plurality of lower-order management devices configured to receive the measurement information transmitted from the wireless terminal devices; and
a higher-order management device configured to be communicable with each lower-order management device, wherein
the higher-order management device assigns, to each wireless terminal device, terminal identification information having a shorter data length than unique identification information, of the wireless terminal device, which is registered therein, and
the wireless terminal device includes, in the measurement information, the terminal identification information assigned by the higher-order management device, and transmits the measurement information.
