Energy Meter based on MCU

The circuit shown is a microcontroller based Energy Meter that uses MCP3905A as its main component, which is an energy-metering ICs that supplies average power information through a pulse with direct drive for mechanical counter. It includes a higher-frequency output supplying instantaneous power information for calibration while conforming the IEC 62053 International Metering Standard Specification. […]
