Measuring mains power consumption

with the STM32x and STPM01

Introduction

This document describes a software and hardware solution concerning the STM32x

microcontroller and the STPM01 power meter for measuring mains power consumption and

also provides hardware and firmware guidelines to interface the STPM01 with the STM32x

microcontroller.

Figure 1 shows the block diagram of the solution. The system described in

this document is the first “brick” to build a complex system for distributed load management.
