DFRobot BME680 Environmental Sensor is a low power gas, pressure, temperature & humidity sensor based on BOSCH BME680 sensor. It is a 4-in-1 multi-functional MEMS environmental sensor which integrates VOC (Volatile Organic Compounds) sensor, temperature sensor, humidity sensor and barometer.
With DFRobot Gravity BME680 Environmental Sensor, you can monitor 4 environmental parameters simultaneously at the most. It is designed for air quality monitor, and due to the MEMS technology, BME680 has a small size and low power consumption. It can be widely used in environmental monitoring, home automation and control, Internet of Things (IoT) wearable device, GPS enhancement, etc.
DFRobot Gravity BME680 environmental sensor provides a Gravity I2C connector, plug & play, easy to connect. With onboard voltage regulator IC and level translator IC, DFRobot Gravity BME680 environmental sensor shows good compatibility. It can be directly connected to 3.3V and 5V systems. Moreover, there is also a SPI connector in reserve for further expansion projects.
With the development of industrialization, air pollution is getting worse and worse. Toxic chemical odors are even common with new furniture. These invisible killers are destroying your health day by day. You do need to concern about your health as soon as possible and DFRobot Gravity BME680 environmental sensor can help make an air quality monitor. DFRobot Gravity BME680, take good care of your health!

DOCUMENTS
Jargon buster
Plain-language definitions for the technical terms used above.
- BME680
- A Bosch environmental sensor chip that measures temperature, humidity, air pressure, and gas-related air quality changes. Seeing BME680 tells you this breakout is built around a specific all-in-one sensor, so you can check library support, accuracy, and datasheet details for that chip.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- 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.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- 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.
