Hi, according to the Data Sheet the range of the AMS IAQ-Core Sensor is as followed:

Sensing range:
450 – 2000 ppm CO2 equivalents
125 – 600 ppb TVOC equivalents

Your project uses higher CO2 equivalents (2100 ppm for 'Poor'). How is this supported? https://www.mouser.de/datasheet/2/1081/iaQ_Core_Datasheet-1890457.pdf

Hi! Theres nothing special about the sensing range, take a look at the datasheet again:

119DFD60-81F1-4A61-9DBA-97C6FF2A38BF

Values over 2000 ppm also provided, also the ranges for the Air Quality is provided by Eve, i’ve used the same thresholds that Elgato used (and also the IAQ sensor is the same one what Eve used in the 1st gen Eve Room)
