  • Per Westermark's suggest is correct. i think the capacitive sensor is easy to do. when water deep, the capacitive value will large. use this capacitive to build a RC oscillator, then measure this oscillator output's frequency, you can know how deep the water is. you need make a Good insulation PROBE pair.
