ABSTRACT

An automatic irrigation control system as being designed to facilitate the automatic supply adequate of water for a reservoirs to fields or domestic crops in all agricultural seasons. One of the objectives of this work is to see how human control could be removed from irrigation and also to optimize the use of water in the process.  The method employed is to continuously monitor the soil moisture level to decide whether irrigation is in needed, and how much water is needed in the soil. A pumping mechanic is   used to deliver the needed amount of water to the soil. The work can be grouped into four, sub-system named power supply, sensing unit, control unit and pumping sub-system which made the automatic irrigation control system
