It is able to measure line voltage and current and calculate active power, apparent power and power factor. \n\nLibDriver HLW8032 is a full-featured driver for HLW8032, launched by LibDriver. It provides effective voltage reading, effective current reading, active power reading, apparent power reading, power factor reading, quantity electricity reading and additional features. LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example basic](#example-basic)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver HLW8032 source files.\n\n/interface includes LibDriver HLW8032 UART platform independent template.\n\n/test includes LibDriver HLW8032 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver HLW8032 sample code.\n\n/doc includes LibDriver HLW8032 offline document.\n\n/datasheet includes HLW8032 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
