ESP32-C3, PT1000 and MAX31865 based temperature sensor node. The data can be accessed through a webpage, hosted on the ESP itself, which displays a convenient live-updating graph. Still a work in progress, as the software was written before the hardware was complete.
To use this, change the IP in plot.js to your ESP's assigned local IP. Create
a cfg.toml file with your wifi credentials, see cfg.toml.example for the
format. If all goes well, you can run the code with cargo run and go to
http://<ESP's local ip>/ (no https!) in your browser and see the live
temperature graph.
(the crate is called oliebol because we are going to use this sensor to fry
traditional Dutch oliebollen on New Year's Eve with high precision :) )
