摘 要：A combination of rising energy costs, a desire for national energy independence, and a growing awareness of the dangers of global climate change is pushing Americans to do what they can to save energy. Consumers now buy more fuel-efficient cars and appliances and are growing more aware of their use habits. While it is easy to see how much gas your car uses, beyond the labeling on major appliances at the point of sale, most consumers are unaware of how much electricity these devices actually use. In this Masters of Engineering Capstone Project we designed and implemented a wireless power monitor which sits on a conventional power outlet and is thin enough that an appliance plugs throughs. The power of the appliance being plugged through our device is monitored. The monitor is powered by either making direct contact with the prongs of the plug or by inductively harvesting through a contactless transformer. The latter case puts severe power restrictions on the mote which we overcame by using low-power hardware and OpenWSN, a network stack intended for low power, low data-rate applications such as ours.
