Hydropi – Pool Monitor
In the articles below I have covered how I set up my Raspberry Pi Pool Monitor with sensors, relay boards, databases and web servers, I really hope you find it useful. If you are interesting in some more details then why not take a look at an overview of the project and what I was trying to achieve, also a parts list.
Raspberry Pi Pool Monitor – Website
This Raspberry Pi pool monitor website makes controlling the associated Hydropi python code much easier. It will allow you to see current and average readings from multiple sensors, set relay timers and change settings. It will also provide you with
