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?
