very interesting chip/module, not available yet.
The BME680 builds on Bosch Sensortec's existing BME280 environmental sensor module. By integrating a new gas sensor, the BME680 delivers superior environmental measurement performance, made possible by the internal compensation and calibration of the gas, pressure, temperature and humidity sensors. The gas sensor can detect Volatile Organic Compounds (VOCs) down to the ppm range.
Pressure accuracy of ±0.12 Pa provides altitude information to ±1m, suiting it for applications such as indoor navigation with floor level tracking. Fast response time for measurement of humidity and ambient temperature enables new applications such as personalised weather information and air quality monitoring.
An offset temperature coefficient of 1.5 Pa/K enables altitude stability over temperature of 12.6 cm/K. This is important in applications requiring the user’s vertical position within a building over a wide range of ambient temperatures.
The BME680 is equipped with both I²C and SPI communication interfaces. Three power modes and oversampling rates for pressure and temperature measurements that can be configured separately help designers to easily adapt the BME680 to different applications. An integrated IIR filter eliminates short-term measurement fluctuations caused by potential environmental influences.
