Gravity: BME688 AI Environmental Sensor (VOC, Temperature, Humidity, Pressure)

Jargon buster

Plain-language definitions for the technical terms used above.

BME680

The BME680 is a Bosch environmental sensor chip that measures temperature, humidity, air pressure and a gas signal used to gauge air quality. The part number tells you a device is built around that specific all-in-one sensor, so you can check its library support, accuracy and datasheet details.

DC

DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.

Gravity

Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.

SPI

A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.

VOC

Volatile organic compounds are gases released from things like paints, cleaners, smoke, and some plastics. A VOC reading helps indicate indoor air quality, but it is usually an index or estimate rather than a direct identification of each chemical.
