Single-phase E-meter for Single-chip Metrology

This design, featuring the MSP430F6736 device, implements a highly-integrated single-chip electricity metering (e-meter) solution. Hardware and software design files are provided to enable calculation of various parameters for single phase energy measurement, such as RMS current & voltage, active and reactive power and energies, powerfactor and frequency.

Features:

• Low-power single-phase e-metering implementation
• Calculate parameters such as RMS current & voltage, active and reactive power and energies, power factor & frequency.
• Based on the highly-integrated MSP430F67xx family of metering-focused MCU SoCs
• Segmented LCD is also implemented in this design.
• RF modules can also be added to this design to enable unique connectivity solutions.
