Microcontroller Based Design of Power Meter
In this paper, the authors present a design of an affordable and convenient means for consumers to accurately measure the power consumption of the electrical devices. If a consumer is able to measure the AC power drawn from a particular household circuit, then they would be able to calculate the cost of operating that piece of equipment. Comparisons could then be made between similar machines, to see which consumes the most energy. In addition, the meter could facilitate troubleshooting a device that maybe causing problems (i.e. frequently tripping a breaker).
