Here is a rough idea of what I am trying to do.

I have a spare raspberry pi 3b+ board. So, what I did is I created a server and a UI that show all the water levels of my tanks (I have 5 tanks in total (4 top on 3 stories and 1 on the ground floor)). I have two motors that are responsible to fill these tanks. One is a 1.5HP motor that is submerged and will be responsible to fill the Top 3 tanks with some ball valve changes overhead. So need that measurement for turning the valves accordingly using a stepper motor(future project in hand).
