The interest in irrigation arises from the most varied conditions of climate, soil, culture
and socio-economics. There is no ideal irrigation system, capable of meeting all these
conditions and the interests involved in an extremely satisfactory manner. In some regions,
farmers irrigate manually. Each cut has an irrigation system that is connected to pipes that
communicate through records to a system for pumping water from a weir or rivers, most of the
time this system chosen to irrigate is the micro sprinkler system. Opening and closing records
for each block (a term used by some farmers to name plantations) is manual. This process causes
the use of water far beyond what is necessary as it also creates the need for the presence of the
farmer to manipulate the records. The automation of a process can involve mechanisms from
the simplest to the most complex, this is made possible through the development of mechanical
and electro-electronic devices that allow activation without human intervention, for example,
the activation and / or deactivation of a process. This work presents the construction of a
prototype to automate the process, it is a simple project. The prototype uses sensors for
humidity, temperature, rain, solenoid valves and a microcontroller. The system relies on pre-
programmed commands to execute the process. Initially the project aims to collaborate with nature and the farmer in order to avoid wasting water and make the process independent of the
presence of a person.
