Hi - I am struggeling like others with the BME280 used in outdoor. Even protected in a box the humidity seems to increase and settle at 100% once ambient temperature goes down. I am using official libaries. #include <Adafruit_Sensor.h> & #include <Adafruit_BME280.h> and the reading is: bme.readHumidity() Now I assume it could be: a) needed protection of the sensor itself against humidity at dewpoints (other communities suggest to wrap PTFE around the BME280 or b) dewpoint compensation, if that is the flaw. For the point b) you had an exachange here on an compensation, which I do really please let me understand where to put this squence of code in and Arduino project. And how to get t_comp? I assume t_mes = measured temperature by BME280. rh_mes = measured. Could you help me out, evtl. with a ready-made code to use? Thank you very much indeed, Manfred
