[DIY Design] Based on HLW8032 electric energy metering system

Overview

The power collection system is composed of STC89C52 microcontroller as the core, HLW8032 as the power collection module, and AIP650 as the digital tube drive module. The system consists of 3 modules. The special differences of the three modules are as follows:
1. The minimum system of L51-01 microcontroller is a system composed of AT89S51/52 or other 51 series compatible microcontrollers and peripheral circuits such as power supply circuit, crystal oscillator circuit, reset circuit and program download.
The L51-01 system leads to all IO ports, and reserves 3 power interfaces VCC (for input power voltage) and GND. The reserved serial communication interface can be used for serial communication of single-chip microcomputer or the program download of STC and other series of single-chip microcomputers. The reserved ISP program download The interface is used to download programs for Atmel and other series of microcontrollers to facilitate users' secondary development.
2. Based on AIP650 driven 4-digit digital tube module, IIC interface, compatible with OLED module interface.
3. Electric energy measurement module based on HLW8032, UART interface, module isolation. It can collect the voltage, current, power, and electric energy of alternating current, and calculate the power factor, etc.
The above, in the form of modules, can be used more flexibly by replacing the microcontroller or display module, making it easier to learn.
