I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them.

Hi all,
Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May.
Hope this helps.
Really nice, did you buy the glass plates from there ?

If not, can you please tell where you get them from ? Thank you !

Perhaps I don't necessarily need to use the same pins
Both the sensors you quote are using I2C. So they both use the same 2 pins (SDA, SCL) to communicate. You can put many I2C sensors on those same pins, they each have an address to know which sensor is receiving/sending data to the master (here, your arduino).
Look for a tutorial on I2C first.
Thanks I get it now
