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.
