This setup allows Arduino to read temperature, control relay based on setpoints, display info on OLED screen, and manage date/time settings with user input through buttons. Adjust based on specific hardware/project requirements.
Designed to replace the faulty electronic control of a blue heat radiator.

it uses the headphone jack as the ADC. the app is called huskerscope.
i made this little board to allow me to have an input
These are pre-generated labels that can be set up after printing. I provide them for free to download here. If you are in the EU you can also buy them printed on a sheet of adhesive paper.

I am doing "prior art" research to find out what are reliable and open constructions of sensors (and controlling/recording) platforms used in citizen monitoring of environment.
Due to recent events in Poland, priority topic is river monitoring:
- water temperature,
- pH,
- conductivity,
- dissolved oxygen,
- turbidity,
- ORP (oxidation reduction potential),
- water level (sonar?).
Also, typical weather station sensors recommendations will be appreciated.
If you know about an active group dealing with river environment monitoring, please drop a link here – I will be happy to learn from them.
At this stage, I do not intend to start any deep R&D. I need to learn about good (best!) practices and appropriate hardware, so we can deploy a network of early warning checkpoints as soon and as cheaply as possible.
