Hello, I have two CO2 Bricklet 2.0's: Bricklet A "blue": bought December 2021. I had no prior experience with a CO2 sensor, but I found the PPM on the high side, as mentioned in this topic. So, I bought another one: Bricklet B "green": bought February 2022. It appears to consistently produce a much lower reading. This week I had the time to mount both Bricklets side by side and log their readings. This is the result: Both Bricklets have been reset and disconnected/reconnected multiple times. Both have been mounted outside in "fresh air" for an entire day. This makes no difference. What am I doing wrong? Am I missing a step?
