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
All VOC/gas sensors have variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparisons. We recommend that you run this sensor for 48 hours when you first receive it to “burn it in”, and then 30 minutes in the desired mode every time the sensor is in use. This is because the sensitivity levels of the sensor will change during early use, and the resistance will slowly rise over time as the MOX warms up to its baseline reading.

PINS USED ON HEROCORE
HeroCore wher pins used by the Air Module are marked. The Air Sensor module uses the I2C plug. Blue is GND, Red is VCC and Orange are SDA (left) and SCL (right). All other holes on the module are not connected.
