The sensor is equipped with a built-in air pressure sensor, which can directly output the values of ambient air pressure, oxygen partial pressure, and oxygen concentration, making it easy for users to intuitively read the data. Compared with electrochemical sensors, AOX4000 uses non lossy oxygen sensitive materials, thus having a longer lifespan. Due to its temperature compensation function, no additional compensation system is required. AOX4000 is very stable and environmentally friendly, without lead or any other harmful substances, and is almost unaffected by cross interference from other gases.\n\nLibDriver AOX4000 is a full-featured AOX4000 driver launched by LibDriver, which provides functions such as oxygen partial pressure reading, oxygen concentration reading, atmospheric pressure reading, temperature reading and so on. 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 AOX4000 source files.\n\n/interface includes LibDriver AOX4000 UART platform independent template.\n\n/test includes LibDriver AOX4000 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver AOX4000 sample code.\n\n/doc includes LibDriver AOX4000 offline document.\n\n/datasheet includes AOX4000 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
