Keyestudio CCS811 needs GND at the WAKE pin?

[blacksurgeon]

Hello Pina,

at first thank you very much for AeVOC. Works great and had a lot of fun building it.
However I have to admit I used a 3D Model for FDM printing as a housing.

Now to the topic.
At first I got no reading from the CCS811 and I was wondering if this has something to do with the Burn In mentioned by you and the Datasheet (https://cdn.sparkfun.com/assets/learn_tutorials/1/4/3/CCS811_Datasheet-DS000459.pdf) from sparkfun.

I found a specific page (https://wiki.keyestudio.com/KS0457_keyestudio_CCS811_Carbon_Dioxide_Air_Quality_Sensor) for my sensor pcb and it seems like the WAKE pin needs GND in order for CCS811 to work. At least now I get measurements.

Now I'm wondering if this is necessarily just for my CCS811 or for all of them?

Best wishes,

Sebastian

Hi Sebastian,
