Gravity BME680 Environmental Sensor

The Gravity module from DFRobot carries the Bosch BME680 and measures temperature, humidity, air pressure and volatile organic compounds (VOC). Voltage regulator and level shifter on the module allow operation on 3.3 V and 5 V boards such as Arduino, ESP32 or Raspberry Pi. It connects via I2C with the Gravity connector, an XH2.54 connector for SPI is prepared.

Alternative with the newer Bosch BME688: Gravity BME688 Breakout Humidity, Pressure, Temperature and Air Quality Sensor

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.

Recommended Accessories:

• Dupont Cables M-M 10cm 20 Pieces

Features:

• Four measurands in one sensor: temperature, humidity, air pressure and VOC (gas resistance)
• Gravity I2C 4-pin, SPI connector XH2.54 6-pin in reserve
• For 3.3 V and 5 V controllers
• Indoor air quality index (IAQ) 0 to 500, higher is worse; according to the product page, DFRobot supports the IAQ calculation only on the FireBeetle ESP8266
• Library and example code for Arduino by DFRobot

Application Examples:

• Indoor air quality monitoring
• Weather station
• Smart home and IoT
