Abstract

A smart solar-based watering system is an alternative step in the agriculture field that has been applied by countries like Bangladesh, India, and Turkey. The implementation of solar technology into an automatic watering system is practical especially as it requires low maintenance with unlimited sources. This project is done to build a watering system that is powered by a photovoltaic (PV) system. The water pump in this project is controlled by a relay module which is activated by a microcontroller (Arduino UNO). A signal is sent to the microcontroller by a soil moisture sensor (FC-28) which is used to monitor the moisture level of the soil by comparing the resistance value of the current flowing through the probes with a reference value. The water pump will operate when the value of resistance is below the reference value which means the soil is dry. The electrical energy produced by the Monocrystalline solar panel is stored in a rechargeable battery which is connected to a solar charge controller to avoid from overcharging. The efficiency of the solar panel is analyzed based on the measured output voltage
