See how to use the water sensor module or water sensor to activate a solenoid valve in this dog drinking fountain project. We programmed an Arduino UNO board connected to a relay module to signal the water level in full, medium and empty, making use of a protobard with three LEDs.
We use a 220 volt solenoid valve, but there are others with lower voltages. We connect an outlet for a faucet on one side and an irrigation hose on the other, in addition to the parallel wire cable.
Here you can find all the details about the electrical circuit and also the programming sketch for the Arduino IDE: docs.google.co...
