The BugPlug power monitor turns off power to devices when no one is present. The simple device uses a heat and motion sensor to determine when a device is being powered, but not being used. It's the perfect thing for households with forgetful people, and for busy parents with children.
The design of the BugPlug power monitor is from Kamil Jerzykowski of Poland and was entered into the 2nd annual Green Gadgets Design Competition. An adjustable timer allows the end user to set the length of inactive time that must pass before power is switched off.
