Sensing line cord current to restart, is fine if pump is wet, but could be damaging to motors running dry. It seems a brief couple second test every few hours should be well tolerated, but probably only of modest utility. I am aware, it is bad to run a water pump dry, the user manual usually says s...

Arduino
Or a PIC.
Or a Orange Pi 0.
There are 20 alternatives to the Raspberry Pi.
Orange Pi, Banana Pi, and plenty more.

Excuse me being pedantic, you need a microcontroller. The name given to a processor chip that includes RAM ROM and peripheral circuits like timers and I/O.

May be not that unreliable when I think of what geeks are capable in sound processing with powerfull microcontrollers that cost near nothing. A challenge in sound recognition ( typo edited ), an artificial intelligence that is likely to come in our homes in the near future. By the sound of the pump ...

Hey.
What about detection based on loudness, sound ?

Congratulations.
A good investment. How long will it take to break even ?

LED lamps. You can roll your own. LED module + constant current power supply + heatsink. Modules from 10W to 100W and compatible CCS are available at very low prices direct from China. Heatsink, I am pretty sure you have or can get from junk. Have fun designing a decent assembly with good protection...

I see, the place is humid.
Pecan tree.
I know of a Pecan tree that gives very poorly but was good before.
Could that be because of insects ?

The typical pattern is that it can take several days to finally get all the water out after it stops raining because more water slowly seeps in from the surrounding ground water. The slitted drain pipes buried into the bottom of the rain ditch will help move ground water out of the area. I am drain...

I see an interesting point. Sensing the pump's motor current, nothing directly involved with water is a very safe solution.

Water together with mains power can be a safety hazard.
