The first prototype of my low-power CO2-Sensor is working! 🎉 It currently consists of:

- ESP32 "feather" devboard
- the CO2 Feather Wing I co-designed, featuring a Senseair Sunrise sensor
- npub1efn0zqsjs9vq0tttlmnkrm5csqmnzazm89u2dfmrm0gfvrz9dt5q7cxgda (npub1efn…xgda)'s E-Ink Feather Friend
- a Waveshare E-Ink display, which shows the current CO2 value in ppm
