    BME680 sensor output - AQI value

    BME680 sensor output - AQI value

    Does AQI output varies with variation in temperature ?

    Is BME680 sensor output temperature sensitive ?

    We had tested sensor inside enclosure of size L*W*H is 30*25 *15 cm

     cable of size  2 .5 sqmm placed inside enclosure

    We ran the BME680 for 2 Hours , it's AQI stabilize to 300 .After stabilitzation passed 20 A current throught cable and AQI dropped to 250

    i guess due to increase temperature casued by 20 A through cable has changed the AQI value

    Hi SESA,
    Temperature and humidity will affect the IAQ output by BSEC.

    Please refer to the HSMI temperature to place the sensor away from heat sources. https://www.bosch-sensortec.com/media/boschsensortec/downloads/handling_soldering_mounting_instructi...

    How much AQI will vary per degree variation in tempertaure

    How much AQI will vary per % variation in humidity

    Hi SESA,

    BSEC library will compensate IAQ value according to temperature and humidity, but no details are disclosed.
