Environmental Sensing Solutions from Bosch Sensortec

Sensors to improve your health and well-being

The Bosch Sensortec family of environmental sensors includes barometric pressure sensors enabling for example indoor navigation and altitude stabilization. Furthermore, humidity sensors measuring air pressure, ambient temperature and relative humidity for climate control in smart homes belong to the category of environmental sensors. Highly integrated four-in-one gas sensors further add gas measurement for air quality monitoring to improve health and well-being.

Pressure Sensors

Bosch Sensortec’s barometric pressure sensors enable a variety of smartphones, wearables and smart home applications. Our very small and low-power barometric pressure sensors stabilize the altitude of drones, enable accurate indoor navigation and improve precise calorie counting in wearables. The pressure sensors work with the piezo resistive principle or the capacitive principle.

Humidity Sensors

Meet the smallest weather station in the world! Bosch Sensortec’s robust humidity sensors are highly accurate, low-power environmental sensors for smart home and IoT applications. A humidity sensor combines barometric pressure, ambient temperature and relative humidity in a one compact package.

BME280 Integrated Environmental Unit

The BME280 is a humidity sensor especially developed for mobile applications and wearables where size and low power consumption are key design parameters. The unit combines high linearity and high accuracy sensors and is perfectly feasible for low current consumption, long-term stability and high EMC robustness. The humidity sensor offers an extremely fast response time and therefore supports performance requirements for emerging applications such as context awareness, and high accuracy over a wide temperature range.

  • Relative humidity barometric pressure
  • Low-power consumption
  • Fitness tracking

BME280 Target Applications

  • Context awareness, e.g. skin detection
  • Fitness monitoring/well-being
  • Home automation control, e.g. HVAC
  • Internet of things
  • GPS enhancement, e.g. dead reckoning
  • Indoor navigation, e.g. change of floor detection
  • Outdoor navigation, leisure and sports activities
  • Weather forecas
  • Vertical velocity indication (rise/sink speed)

Gas Sensors

Bosch Sensortec’s gas sensors are highly integrated four-in-one environmental sensors combining barometric pressure, ambient temperature, relative humidity and gas measurement in one small package. They detect a broad range of gases including Volatile Organic Compounds (VOC) for air quality monitoring in smart homes.

BME688 Environmental Sensing with Artificial Intelligence

The BME688 is the first gas sensor with Artificial Intelligence (AI) and integrated high-linearity and high-accuracy pressure, humidity and temperature sensors. The gas sensor can detect Volatile Organic Compounds (VOCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. Additionally, to all functions of the BME680, the BME688 comes with:

  • Specific detection of VSCs
  • Application-specific gas scanner
  • BME AI-Studio

BME688 Target Applications

  • Indoor and outdoor air quality measurement
  • Bad breath or spoiled food detection based on the measurement of Volatile Sulfur Compounds, which are an indicator of bacteria growth
  • Detection of unusual gases and smells, which might indicate for instance a leakage or fire
  • Diaper state detection, e.g. for baby care
  • Early detection of bad smells
  • Wildfire detection
