The DFRobot Gravity BME680 sensor simultaneously measures temperature, humidity, atmospheric pressure, and volatile organic compounds (VOCs), supporting air quality monitoring. It is based on the BOSCH BME680 sensor and uses MEMS technology for low power consumption. It connects via Gravity I2C and has an SPI expansion socket.
