## Description

The BME688 from Bosch delivers comprehensive environmental sensing in a single compact package. This precision sensor measures temperature, humidity, barometric pressure, and VOC gas levels, all accessible over I2C or SPI. The BME688 is a drop-in replacement for the BME680, adding a programmable gas-sensor heater for controlled odour analysis. This enables machine-learning-based odour detection while retaining all the environmental sensing capabilities of its predecessor. The onboard MOX (metal oxide) sensor detects volatile organic compounds such as ethanol and carbon monoxide, providing an overall VOC resistance value for air quality monitoring. Key Features Temperature – ±1.0°C accuracy Humidity – ±3% relative humidity accuracy Barometric Pressure – ±1 hPa absolute accuracy Altimeter – ±1 metre accuracy (derived from pressure) VOC Gas Sensor – Heated MOX element with programmable heater for odour analysis Dual Interface – I2C and SPI communication STEMMA QT / Qwiic – Plug-and-play I2C connectors, no soldering required Voltage Range – 3.3V or 5V operation via onboard regulator and level shifting Also Available Adafruit BME680 – Same sensor family without programmable heater Adafruit BME280 – Temperature, humidity, and pressure (no gas sensing) Ideal For Indoor air quality monitoring and odour detection Weather stations and environmental logging IoT environmental sensing projects Machine-learning-based gas classification Note: Like all VOC/gas sensors, the BME688 has variability and should be calibrated against known sources for precise measurements. Run the sensor for 48 hours on first use to "burn it in", then allow 30 minutes of warm-up each time it is powered on. Package Contents 1× Adafruit BME688 breakout board with headers

**Product Type:** physical
