BME680

Gas sensor measuring relative humidity, barometric pressure, ambient temperature and gas (VOC).

The BME680 is the first gas sensor that integrates high-linearity and high-accuracy gas, pressure, humidity and temperature sensors. It is especially developed for mobile applications and wearables where size and low power consumption are critical requirements. The BME680 guarantees - depending on the specific operating mode - optimized consumption, long-term stability and high EMC robustness. In order to measure air quality for personal wellbeing the gas sensor within the BME680 can detect a broad range of gases such as volatile organic compounds (VOC).

Possible use cases:

  • Personal air quality tracker
  • Air quality mapping
  • Air quality inside cars & public transport
  • Enhanced context awareness
  • Accurate step & calorie tracker
  • Quick GPS-fix & improved navigation
  • Indicator of too high / low humidity
  • Air quality & well-being indicator
  • Sleep / recovery tracker
  • Weather trend
  • Stair counter
  • Floor level detection
