An AVR-based power usage logger

October 22nd, 2008 by miked

AVR Power Use Meter

Dan wanted to monitor the power usage for his house. He installed some current sensors made from a couple of TV flyback transformer cores. The voltage is stepped down by another circuit. Then both the voltage and current are amplified to the correct levels and the ATmega168 microcontroller computes the power consumped using the formula P=V*I. A graphic LCD shows the power usage and can also display the voltage and current waveforms. All logs are then saved to an SD card. <via MCU Project Everyday>
