## LibDriver BME690

[![MISRA](https://img.shields.io/badge/misra-compliant-brightgreen.svg)](/misra/README.md) [![API](https://img.shields.io/badge/api-reference-blue.svg)](https://www.libdriver.com/docs/bme690/index.html) [![License](https://img.shields.io/badge/license-MIT-brightgreen.svg)](/LICENSE)

BME690是小巧的四合一空气质量传感器，用于监测室内空气质量，能够检测挥发性有机化合物(VOC)、挥发性硫化合物(VSC)及其他气体。BME690是基于BME688进一步开发的型号，耐用性增强，适用于高冷凝水平的环境。

LibDriver BME690是LibDriver推出的BME690全功能驱动，该驱动提供大气压强，温度，湿度和气体读取等功能并且它符合MISRA标准。
