Dear Team, We are using BME280 to monitor humidity and temperature. Temperature is working as expected but humidity has got an offset always. We have bought a couple of humidity sensors, which will be the reference humidity value. You can see from the above graph that all the BME280s (green lines) are having a negative offset on the humidity value (RED is the reference). We are using the APIs from the Bosch sensortec github. Why do you think there is an offset ? The datasheet says the reconditioning procedure is mandatory after soldering process. We haven't done the reconditioning. Could that be the reason for the offset ? Also, could you please suggest us the best way to do the reconditioning ? Are there any standard device which can do the reconditioning in the production ?
