To provide a central management system capable of performing central management on an electric apparatus and a sensor device, and capable of reducing power consumption of the electric apparatus and the sensor device.
There is provided a central management system at least comprising a central management unit, an electric apparatus or a sensor device, and output means. The central management system carries out arithmetic calculation on information transmitted from the electric apparatus or the sensor device, and causes the output means to output information according to a result of the calculation. A user is allowed to know a state of the electric apparatus or the sensor apparatus even when the user is away from the electric apparatus or the sensor device. The electric apparatus or the sensor device includes a transistor which uses a semiconductor having a wider band gap than that of a single-crystalline silicon as an active layer.
