This device interfaces with an MH-Z19B and makes the data available in home assistant via esphome. It could also work with any other software you'd like on an ESP32.

What's included

A ready-to-go circuit board with an ESP32-C3-MINI, an MH-Z19 compatible header for a cable if you wish, or with the set of pin sockets. This might also work with the Senseair S8 as it has the same pinouts.

The actual CO2 sensor is not included.

Programming

Hold the button while plugging in the device the 1st time you program the device. After that, all subsequent flashing, either via USB or OTA, do not require the use of the button.

This now supports native USB-C programming on the ESP32-C3-MINI. If you wish, there is an auxiliary header. The programming header can work with any esp32 programmer if wired up correctly. The pinout matches my esp32 programmer, eflashy32 if you are in need of a programmer as well.
