I need a WiFi capable board that will be used to monitor tank water level. The data gathered will be saved to the cloud and used for a real-time usage graph. Each tank has WiFi installed. I actually need to monitor two tanks, but will begin with one to start with.
The tanks are about 0.7 miles apart. I am including this info just in case it may have some bearing in choice of boards. I hope to be able to send this data to a cell phone app.
I would like to have the board powered by both a 5V (converted from 120V) and also have a LiPo battery for backup in case of power failure.
These water tanks feed 60 households and a rapid drop in water level can have serious consequences to these families. This is usually due to line breakage (construction crew) or user(s) forgetting to close a waters spigot. This is why the level monitoring in real time is critical.
Any help in board selection will be greatly appreciated.
