some weeks ago I got a new SCK2.1 and am very uncertain, why the eCO2 and TVOC readings are so exorbitantly high. I have an older SCK2.1 and put this the days of 28th of March 2023 till 1st of April 2023 right beside each other and the readings are so different. The new one is much after a burn-in time of 48 hours. You can see values of readings here:
and here the readings from the older SCK2.1
Hope anyone can give me some help, as I am very disappointed on the differences and unsure what to do.
