Overview

The Adafruit BME680 is a multi-sensor breakout board that measures barometric pressure, humidity, ambient temperature, and volatile organic compounds (VOCs) using a Metal-Oxide (MOX) gas sensor. It features an integrated 3.3V regulator and level shifting, allowing it to interface easily with 3V or 5V logic controllers via I2C or SPI.

Why Choose This Part

This breakout simplifies integration by including STEMMA QT / Qwiic connectors for solderless I2C connections and on-board level shifting for 5V compatibility. The Bosch BME680 sensor provides high-linearity and high-accuracy sensing across four distinct environmental parameters in a single compact footprint.

Applications

Indoor Air Quality Monitoring
Calculate the Air Quality Index (AQI) by monitoring gas resistance changes alongside humidity and temperature data.
Environmental Weather Stations
Capture precise barometric pressure, humidity, and temperature for local weather forecasting and altitude tracking.
HVAC Control Systems
Optimize ventilation and climate control in smart building applications based on real-time air composition and thermal conditions.

Getting Started

Connect the board via the STEMMA QT header or the breadboard-friendly pins to any microcontroller like an ESP32 or Arduino. Use the Adafruit_BME680 library available in the Arduino Library Manager or the CircuitPython library to begin reading gas resistance and environmental data immediately.
