Hello.

1 phase. voltage, current and Power.

-The voltage range is 220v AC.

-The current range is 0 to 20A.

1. Use MSP430FE42x MCU with shunt resistor.

Hi

Use the ADE7753 from analog with SPI interface to microcontroller - remember to isolate the SPI interface from the mains voltage.

All the best
