 The sensors are connected to an ESP8266 with an 8mm PL9823 RGB LED (which uses WS2812B protocol, except it's RGB, not GRB). They're wired up on a (very annoyingly: double-sided) perfboard. There's a logic level shifter for the data pin of the RGB LED, circuit diagrams will be posted at some point.
-The ESP8266 runs esphome, the configs are available on [[https://esphome.z9.ccchh.net/|our esphome instance]]. For some reason it cannot connect to the devices, so you'll still want to flash them through your computer or something (for now I'm using it as just a config storage).

 For sensor choice justification see [[https://queer.party/@ao/111779978098588711|this fedi post]], TL;DR: NDIR sensors are the only cheap, small and good way to get CO2 data currently, and many other cheaper options require a lot more maintenance due to their calibration logic being worse.
