BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables where size and low power consumption are key requirements. Expanding Bosch Sensortec’s existing family of environmental sensors, the BME680 integrates for the first time individual high linearity and high accuracy sensors for gas, pressure, humidity and temperature.

SKU: SEN0248
Provides an Arduino library for reading and interpreting Bosch BME680 data over I2C over SPI.Reads temperature, humidity, gas, IAQ(details in examples\readme), pressure and calculates altitude.
To use this library download the zip file, uncompress it to a folder named DFRobot_BME680. Download the zip file first to use this library and uncompress it to a folder named DFRobot_BME680.
