When water comes in contact with the sensor probes, it completes the circuit due to the conductivity of water. This allows a small current to flow, which is used to trigger the circuit.
Once activated:
The LED glows, indicating the presence of water.
At the same time, a relay gets energized, which can be used to control external devices like a pump, alarm, or any electrical load.
The circuit is very useful for applications such as:
Water level detection
Rain alarms
Leakage detection systems
