    I want to impliment a PC-based data logger for my home energy usage by
    measuring my total current, voltage, and power readings at my main
    breaker.

    I know there are products that do this and have various read-outs and
    data logging capability.

    I don't want a readout, and I don't want data logging capabilities.

    Do any modules or devices exist where I can attach a couple of coils to
    measure current on my 2 hot leads and three wire connections to measure
    my 2-phase 220 VAC service, and generates numeric data I can read via
    serial interface by a PC with a time resolution of my choosing?
