By using patented conductivity conversion algorithm and temperature correction algorithm, the detection of aqueous solution conductivity can be quickly achieved, and automatic temperature correction can be achieved over a wide temperature range to reduce measurement errors caused by changes in conductivity values with temperature.\n\nLibDriver BA121 is a full-featured driver for BA121, launched by LibDriver.It provides conductivity reading, temperature 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 BA121 source files.\n\n/interface includes LibDriver BA121 UART platform independent template.\n\n/test includes LibDriver BA121 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver BA121 sample code.\n\n/doc includes LibDriver BA121 offline document.\n\n/datasheet includes BA121 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
