This project is a printed circuit board (PCB) for use of SCD30 environment sensor with the ESP8266 controller. This PCB also includes a built-in USB-UART bridge and can be programmed via the USB-C port without any external tools.
In this repository you can find all associated files as EasyEDA Pro project files, datasheets for sensors and used components and ESPHome firmware example.
Use the esphome-sample-project.yaml file as an example configuration for the ESPHome firmware.
Unfortunately, the ESPHome web_server component does not really support the storage of the values' history. Even the v3 version of the web_server only uses the values on the client side. So, after the page reload the values' history is not available.
With the history_container component in my ESPHome fork and the adapted included web-server you are able to store the history of last N values on the ESP8266 itself and make your sensor fully self-contained.
