A power control system development by Zigbee is proposed in order to control the power
used by an electronic appliance remotely. A status of power usage can be investigated and
informed to the user via an internet and a mobile phone. Therefore, the appliance can be turned
on or turned off as a user requirement. Zigbee, a wireless sensor network, is used to develop a
wireless control especially an embedded application. Since it is a low cost and a low power
technology, a long-life usage is allowed.
