Connection Diagram
The water sensor have 3 pins, we connect the negative to GND, the positive to 5V and the S pin, the one we use for
the GPIO to AINT0. Once the circuit is closed by watering touching the surface of the water sensor it will send signal
to the AINT0 pin and we'll be able to know the amount of water over the sensor.
