Thisi is BSEC introduction: BSEC library provides higher-level signal processing and fusion for the BME680. The library receives compensated sensor values from the sensor API. In order to fully provide the requested sensor outputs, Bosch Sensortec environmental cluster processes the BME680 signals and combines them with the additional phone sensors. The BSEC library offers a complete, easy to integrate software fusion solution out of one hand and thus eliminates the need for own fusion software development.
