Auto-Irrigation System with PV Solar Tracking

The objective of this paper is to design and construct an automatic irrigation system powered by PV panels on a laboratory level. The paper states that the utilization of a photovoltaic (PV), off-grid solar system could be the solution for pumping and irrigation systems in Palestine. The methods used here include using a humidity sensor in the soil and temperature sensor in the air to test the need for the irrigation system.
