Fermion BME688 AI Environmental Sensor (VOC, Temperature, Humidity, Pressure)

The Fermion BME688 from DFRobot is a small breakout with the Bosch BME688 for temperature, humidity, air pressure and volatile organic compounds (VOC). A heating layer under the chip keeps the gas measurement stable and allows gas profiles for AI evaluation with Bosch BME AI-Studio. The module measures 18 × 15.6 mm, connects via I2C or SPI and comes with a pin header for soldering.
