Hi Minhwan, i downloaded the new software and renew my code. See below. I changed the power mode to LP, because I'm interested in the air quality and do not search for a specific gas. Additional I updated the associated files. When I'm using the newer libalgobsec.a the system seems more agile and realistic, but the CO2 value starts at 600 and do not go below. Why? Even though I'm sitting next to an open window, I don't get the low value. Additional the values of temperature and humidity in both library version have a big difference. Which version should I use? I attach the log file, where both versions are included. During both measurement I have blow to the sensor. Thanks.
