CO2 Sensor Crystal

The electronics includes an Emakefun Nano V3 Plus, the CO2 sensor MH-Z19C-DZ, 3 Adafruit NeoPixel Diffused 8mm Through-Hole LEDs and various connectors, cables and a small PCB.

The printed crystal definitely needs to be reworked and adapted to the PCB and the position of the LEDs. After positioning the crystal, I fixed the "LED_Einsatz" to "Base_Steine" with adhesive tape. This prevents the crystal from twisting.
