Product Introduction

️ BME680/BME688 is a four-in-one environmental sensor launched by Bosch Sensortec, integrating temperature, humidity, air pressure (barometer) and gas (VOC) detection functions. It features a low-power design and is suitable for Internet of Things (IoT), smart homes, weather stations and wearable devices.

The module is equipped with STEMMA QT/Qwiic interfaces, supporting plug-and-play I²C communication without soldering. It can be directly connected to Adafruit, SparkFun, Raspberry Pi, Arduino (QWiIC-compatible devices).
