Fermion: Multifunctional Environmental Sensor (Breakout)

This compact multifunctional environmental sensor combines four professional sensor chips into a single breakout board: SHTC3 (temperature and humidity), BMP280 (barometric pressure), VEML7700 (ambient light), and ML8511 (UV). An on-board MCU converts raw sensor data into standard units, so you get ready-to-use readings without complex calibration.

Supporting both UART and I2C communication, the Fermion breakout version is designed for direct PCB soldering. Complete Arduino and Python libraries are provided for quick integration.
