I live in Texas where we are having worst drought on record - and our only source of water which is a shallow well is getting low. I would like to be able to monitor that level remotely since the well is 300' away. Looking for ideas.
I currently have a 10 turn 500 ohm pot on a 1 foot circumference pulley that I can use with a float to generate a variable resistance depending on water level. There is a 3 wire power line going to the well - no ground. Running another wire is not practical.
I am electronically savvy but out of date - think discrete component power amps. I also teach computing at local junior college so some kind of PC input (usb) would be interesting.
Thanks ahead for any input
