1. A wireless sensor system comprising:
a wireless terminal device which is driven by electric power stored in a power storage unit, and is configured to transmit measurement information indicating a result of measurement by a sensor;
a relay device configured to relay information received from the wireless terminal device; and
a management device configured to receive the measurement information relayed by the relay device, wherein
the wireless terminal device transmits a preparation request,
the relay device receives the preparation request transmitted from the wireless terminal device, and relays the preparation request to the management device,
the management device receives the preparation request relayed by the relay device, and transmits, to the relay device, setting information related to the wireless terminal device,
the relay device receives and holds the setting information transmitted from the management device,
after transmission of the preparation request, the wireless terminal device transitions to a first sleep state to stop a communication operation, and transmits a setting request after returning from the first sleep state, and
the relay device receives the setting request transmitted from the wireless terminal device, and transmits the setting information held therein to the wireless terminal device.
