Summary

This is a module (hat) for the Flipper Zero, to house a MH-Z19 CO2 sensor. It's designed to fit snug against the flipper, and is not compatible with a case. I designed it this way to avoid bending any pins and make it look flush. I will also include a version that's open in the middle so other payloads that fit could be used.

Parts:
-MH-Z19C (with pins)
-26AWG wire or whatever
-proto board (cut to fit)
-0.1" through-hole header pins
-(2) M1.7 x 6mm screws or super glue if you're feeling confident

Solder all pins to proto board, then wire to MH-Z19 as follows:
MH-Z19 pin (flipper pin):
-Vin(1)
-GND(8)
-RX(15)
-TX(16)

I recommend the MH-Z19 UART App in, however note that as of writing the github has incorrect pinout listed (at least for my MH-Z19)
