Adafruit BME680 Temperature, Humidity, Pressure and Gas Sensor - STEMMA QT

The Adafruit BME680 from Bosch is an all-in-one environmental sensor that measures temperature, humidity, barometric pressure, and VOC gas in a compact breakout board.

Key benefits include:

• Temperature sensing with ±1.0°C accuracy
• Humidity sensing with ±3% accuracy
• Barometric pressure sensing with ±1 hPa accuracy, usable as an altimeter with ±1 meter accuracy
• VOC gas sensor (MOX) for detecting volatile organic compounds such as Ethanol, Alcohol, and Carbon Monoxide, providing overall air quality trends

This sensor operates over SPI or I2C and includes a 3.3V regulator and level shifting for easy compatibility with 3.3V or 5V microcontrollers. The breakout comes with standard 0.100" pitch headers and STEMMA QT connectors, enabling plug-and-play integration with compatible cables (sold separately).

Please note: VOC sensor readings require calibration for precise measurements; the sensor needs a 48-hour burn-in period on first use and about 30 minutes warm-up each session for stable readings.
