CO2 chamber: Earlier prototypes on Hackteria wiki and github

Nice to see this dedicated category here.

I have been presenting our HUMUS sapiens prototype back at the GOSH 2018 in Shenzhen. Slammed it on the table… (and yes it did break of some wiring :slight_smile: )

We docmented the CO2 soil respiration chamber on the hackteria wiki here:
https://www.hackteria.org/wiki/CO2_Soil_Respiration_Chamber

And just recently during the UROŠ activities we updated the hardwares, using esp32-s2 and the new sensor SCD41 sponsored by Sensirion (i am working to get more)

I will work in this again in the coming weeks. Working closely with @nanocastro on this. But ping here if you are interested to join the research, as hardware dev, software implementation or especially field use!
