Objective of this study is to design and construct the automatic irrigation equipment controled by computer. The control unit composes of three different components. The first is climate station which records data such as temperature, relative humidity, solar radiation, wind speed, rainfall and barometic pressure. The second is control program unit that gets data from climate station and processes them and gives a signal to the third unit-commonly called a circuit unit. When this unit receives a signal from the second unit, pump and solinoid valve is operated until soil moisture level is field capacity.
