Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

Note that with the “DFR” sensor, we get a signal output very close to VCC (in digital mode) when the sensor is not submerged or is in clear water (and a bit lower than that in analog mode). Here’s one ...

The cloths pin and aspirin water sensor is quite old – I remember seeing it in an electronics magazine in the 50s or 60s as a rain detector for parked convertables.
