This work presents the development of an Arduino-controlled irrigation system utilizing a capacitive soil moisture sensor. The prototype is powered by two independent sources: a solar configuration with energy storage and a primary battery backup, ensuring complete autonomy under any condition. The implementation of a MOSFET driver enables proportional (PWM) control of the water pump; power output is modulated according to the water deficit, thereby eliminating traditional ON/OFF cycles and maximizing overall system efficiency.
Il lavoro illustra lo sviluppo di un sistema di irrigazione gestito da Arduino tramite un sensore di umidità capacitivo. Il prototipo è in grado di alimentarsi da due fonti indipendenti, una solare con accumulo, e una di riserva a batterie primarie, così da garantire autonomia totale in qualsiasi condizione. L'uso di un driver mosfet permette un controllo proporzionale (PWM) della pompa, la potenza viene modulata in base al deficit idrico, eliminando i cicli on/off massimizzando l'efficienza del sistema.

Abstract
This work presents the development of an Arduino-controlled irrigation system utilizing a capacitive soil moisture sensor. The prototype is powered by two independent sources: a solar configuration with energy storage and a primary battery backup, ensuring complete autonomy under any condition. The implementation of a MOSFET driver enables proportional (PWM) control of the water pump; power output is modulated according to the water deficit, thereby eliminating traditional ON/OFF cycles and maximizing overall system efficiency.| File | Dimensione | Formato | |
