## LibDriver BME688

[![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/bme688/index.html) [![License](https://img.shields.io/badge/license-MIT-brightgreen.svg)](/LICENSE)

BME688是首款配备人工智能（AI）且集成了高线性度、高精度压力、湿度和温度传感器的气体传感器。该气体传感器能够检测到十亿分之一（ppb）范围内的挥发性有机化合物（VOC）以及其他气体，如一氧化碳和氢气。

LibDriver BME688是LibDriver推出的BME688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。
