Sistema de control de riego para finca agrícola y ganadera, basado en sistemas micro programables.

Abstract

In a modern society, maintaining a large agricultural farm is complex, because the plants dehydrate due to lack of irrigation. To avoid this, it is proposed to project an automatic irrigation system applicable to a farm, which combines free hardware and software solutions, to measure the humidity of the earth, because they are part of the orchard ecosystem. This solution is controlled from an Arduino Microcontroller, which acts as an operations center to ensure the supply and dosage of water, by means of a water pump and an activation relay to keep plants hydrated. The UML modeling helped to identify the actors present in the irrigation system, that is, users, technicians, and the farm. In the use case diagram, 6 actions are described in which they participate, in the sequence diagram 12 processes are carried out during the operation of the system and in the state diagram the actions of the Aroma irrigation system are described in general. Modeling with the Petri net allowed observing the operation of an irrigation system and identifying the different processes that take place there. After determining a series of process variables, such as humidity level, water tank level, temperature, and pump pressure, it was possible to verify that when the system starts when these variables are within the correct range.
