    I'm trying to measure the voltage/current of a home appliance with a TI msp430 microcontroller (basically making my own Kill-A-Watt) and am having trouble researching the correct sensors to measure this range of voltage/current. Does anyone have any suggestions? I'm using the 430 because it has a built in transmitter and want my measured values transmitted to a home computer.

    I'm also trying to power the uc from the same wall outlet I'm measuring. Besides my DBR, I figure I'll need some kind of voltage regulator. Does anyone know what kind of regulator can interface with this kind of power source?
