BME688 has all features of BME680 with an additional gas scanner function.

This breakout comtains the recently introduced Bosch BME688 4-in-1 environmental sensor with AI. The BME688 is the next-generation environmental sensor after the BME680. Further, it is marketed as having AI capabilities.

The BME688 breakout board integrates BME688 which is the newest Bosch Sensortec environmental sensor for humidity, pressure, temperature and indoor air quality sensor with digital I2C and SPI interface. The BME688 is the first gas sensor with Artificial Intelligence (AI) and integrated high-linearity and high-accuracy pressure, humidity and temperature sensors. This small sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities all over SPI or I2C interface. The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. In standard configuration, the presence of VSCs is being detected as an indicator for e.g. bacteria growth. And the gas scanner can be customized with respect to sensitivity, selectivity, data rate and power consumption as well.

STEMMA QT / Qwiic 4-pin 1mm Pitch White Female Connector Cable 150mm Long - Both Side can be purchased seperately.
