Hi all,  I am trying to use the BME680 sensor without the library as I am a raspberry pi user. I am outputing the resistance value of the sensor. Even after turning it on for a day, why is the resistance still going up? It increases from 100k to 400k ohm..... May I know what's wrong wit it?  Thanks 🙂  ... View more

I have a question regarding the VOC accuracy. I was looking online, it seems that there is a variable called BSEC_OUTPUT_BREATH_VOC_EQUIVALENT that will give me the concentration VOC in ppm. Assuming I am interested in measuring the concentration of ethanol (2 ppm at most), what's the accuracy of the measured value?  In the data sheet, it mentions Sensor-to-sensor deviation +/- 15% +/- 15. Does it mean the accuracy of the measused VOC concentration will be BSEC_OUTPUT_BREATH_VOC_EQUIVALENT*0.15 +/- 15? ... View more
