It's very easy to monitor things (like farm tanks) by creating web pages. That way you can view one or more sensors using your phone or computer. As long as they're in range of a wifi signal.
You can do this with one of the raspberry pi models, or with esp8266 (much cheaper and lower power, so more suitable for a solar powered setup).
Difference, other than price, is the Raspberry Pi is a full-fledged computer, so you can write your programs in Euphoria, rather than C. You can also log in via VNC, and have full access to the Raspberry Pi.
Cautions: inputs for these are 0-3.3 volts. Hooking up sensors which commonly have a 0-5 volt output can fry the pie. Esp analog input is 0-1 volt. Same warning. Optical isolated level changers are available for a couple of bucks.
