Design of a UPS Outlet System Controlled by PDAs and GSM Cellular Phones

This paper describes a remotely controllable UPS outlet system for home power management that has developed. The CUPSO (Controllable UPS Outlet) integrates multiple AC power sockets, a UPS and a low-power microcontroller into a power outlet to switch the power of the sockets On/Off, to protect a sudden loss of the AC power supply and to measure the power consumption of plugged-in electric home appliances. Using Bluetooth, the wireless system can control the home electric appliances at home without new wiring. The remote control also provides the user with the ability to control the power On/Off of home appliances through the Internet.
