Part 1 – Hardware and Software Setup || Part 2 – Azure Setup || Part 3 – Dashboarding and Workbooks || Part 4 – Alerting || Part 5 – Tips and Tricks

In Part 5, I have a couple tips and tricks.

I don’t like the idea of having a plug near my Hot Tub so I purchased some of these connectors to go from SMC to BNC.



Then I ran 3 33ft standard BNC cables from my basement to my raspberry PI to the sensors in my hot tub.

After a while my ORP and PH sensors wore out after being submerged in water for over a year.

I purchased this cheaper ORP sensor that works better and last longer. Link

I also switch to this PH Sensor. Link
