According to limited available water resources and water crisis, water resource management and increasing productivity in the agricultural field as the most important and largest part of water consumption is an inevitable necessity. The most important activities in this direction is planning for a suitable irrigation system which can save water- that is the main target of modern systems- and increase productivity in time and user accuracy. Pressurized irrigation systems and consequently the systems that work with variable rate technology in response to the needs and initial targets, showed optimal performance. To respond to the other needs, including productivity in time and reducing human error that affects the system performance, the need for intelligent automatic systems is considered. In this study, the design and production and evaluation of an automation and automatic system on variable rate sprinklers that was made by ROSHAN in 1392 is done.
