AVR Power Usage Logger using ATmega168 microcontroller
This ATmega168-based project monitors household power usage and logs it to an SD card. Signals from voltage and current detectors amplified LMC6484AIN quad op-amp and then AVR microcontroller computes the power consumption using the formula P=VxI. The voltage and current are each sampled at 9615 Hz so the integration should be fairly accurate even for […]
