1. A sensor network system comprising:

  • a plurality of sensor master devices at different positions;

    a data server;

    a plurality of notification devices at different positions; and

    a terminal device including an operation unit for a display screen,wherein the display screen includes a layout display of a sensor, the plurality of sensor master devices, and the plurality of notification devices,wherein the terminal device, in operation, displays the display screen on a display unit,wherein the plurality of sensor master devices includes a first sensor master device and a second master device that are disposed in a sensor reaction area,wherein the first sensor master device is connected to the sensor by wireless communication,wherein the plurality of sensor master devices and the data server are connected to each other by wired communication including power line communication,wherein the data server and the plurality of notification device are connected to each other by wired communication in which at least a portion of a communication route includes power line communication via the plurality of sensor master devices, andwherein the first sensor master device, in operation, receives detection information for the sensor reaction area from the sensor,wherein the data server, in operation, acquires the detection information from the first sensor master device, determines whether or not to perform a notification on the basis of the detection information acquired from the sensor, and executes the notification corresponding to the detection information for at least one of an object to be notified and notification contents in a case where the data server determines to perform the notification,wherein, in a case where the data server determines to perform the notification, the data server transmits notification information corresponding to the detection information to the terminal device,wherein, in response to the terminal device receiving the notification information, the terminal device includes a layout display of the sensor reaction area having the first sensor master device disposed therein, in the display screen, andwherein, in response to the sensor reaction area being selected as a notice area by a selection operation using the operation unit, the data server transmits the notification information to a notification device of the plurality of notification devices via the second sensor master device.
