Adafruit BME688 - Temperature, Humidity, Pressure and Gas Sensor

The versatile BME688 from Bosch integrates advanced environmental sensing in a compact form. Equipped with temperature, humidity, barometric pressure, and VOC gas sensors, it communicates over SPI or I2C.

The BME688 improves upon its predecessor by allowing gas-sensor heater programming for odor analysis, while maintaining ±3% humidity, ±1 hPa pressure, and ±1.0°C temperature accuracy.

Incorporating a MOX sensor, it detects gasses like Ethanol and Carbon Monoxide, offering overall VOC measurements. Calibration is recommended for precise readings.

Designed for convenience, the sensor is mounted on a PCB with a 3.3V regulator, alongside level shifting for use with 3.3V or 5V microcontrollers, and connections via standard pitch headers. Stemma QT connectors simplify integration, eliminating soldering.

Comprehensive resources, including Arduino and CircuitPython code, schematics, and wiring diagrams, facilitate seamless integration into your projects.
