It includes a 2.4 GHz BLE-enabled radio transceiver, a Cortex M4F microcontroller, and a host of hardware peripherals. The device is capable of extracting current and voltage waveforms from a standard wall power plug without contacting the mains power. The current is measured inductively, as a mild steel flux guide channels magnetic flux through a sensitive hall effect device. The voltage is measured capacitively, as the flux guides couple with the conductors in the plug. Measuring both quantities allows us to separate active from apparent power, measuring the real power used by an appliance plugged through our device. bc832-watt/ includes source files for a PCB built around the BC-832 module (containing the nRF52) from Fanstel. - \ No newline at end of file + -- GitLab
