Gravity: I2C BME680 Environmental Sensor

The DFRobot BME680 Environmental Sensor is a low-power gas, pressure, temperature & humidity sensor based on the 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 this sensor, you can monitor 4 environmental parameters simultaneously at the most. It is designed as an 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 devices, GPS enhancement and more.

The sensor provides a Gravity I2C connector, plug & play, easy to connect. With an onboard voltage regulator IC and level translator IC, it provides good compatibility for numerous controller types. It can also be directly connected to 3.3V and 5V systems. Moreover, there is also an SPI connector in reserve for further expansion projects.

Note: The IAQ (In-Door-Quality) calculation function is only supported on the FireBeetle ESP8266 Microcontroller.
