If you ever wondered what is inside an SCD41 CO₂ sensor, then wonder no more.

I was trying to get it off the PCB, but ended up removing the cap - they must have super glued it on there or something...

Quite amazing.

Just done the #ikeaHack #VINDRIKTNING with an esp8266 and #espHome and now it shows in my #homeAssistant

But I also added a #SCD41 co2, temperature, and humidity sensor.
They're kinda expensive but they are actually sensing co2 not just estimating it based on other readings. At least I hope so for the cost.

Will do a blog on it another day, not that this hack needs even more blogs!

Salvaging tiny wires (not just cells) from vapes is worth it for little jobs like this!

Here it is under test
