BSEC proper Humidty/Temperature Calibration?

Hello

I use the BSEC v1 Library to use a BME680 in my Arduino Project, i would like to calibrate the sensor using a precise already calibrated reference Sensor (so atleast all sensors i have in projects show the same values)

Now im wondering whats the best way to get there?

i saw the BSEC Library has just a "settempoffset" parameter and i imagine i need a 2 point offset-slope to get max accuracy right?

i couldnt find in the library a way to calibrate Humidity, is there a easy way for that i just dont see?

Hello Ricky666,

we use temperature_offset in bsec_iot_init as input for BSEC_INPUT_HEATSOURCE for BSEC. Then the calibrated temperature and humility will be send out in outputs of BSEC_OUTPUT_SENSOR_HEAT_COMPENSATED_TEMPERATURE and BSEC_OUTPUT_SENSOR_HEAT_COMPENSATED_HUMIDITY.

we use dew point to calibrate the temperature and humidity, however we cann‘t give more details on this since this is in the source code of BSEC.
