Abstract:
With to growing need of the use of the water with larger efficiency avoiding your waste
and the stress hidric of the culture, the objective of this work was to simulate the operation of a pivot-
central one through the use of a step motor. The area regarding the pivot-central that is of 360° it was
divided in four sub-areas with angles of 90°, and in each one of them was used sensor for the reading
in real time of the humidity of the soil (humid soil and dry soil). The readings obtained through the
sensor ones they were correspondents for the microcontrolador that compared those information with
pré-programmed data, working or turning off a bomb of connected water to a microaspersor. The
sensor ones used they were capable to identify the humidity of the soil in real time, those referring
data to the humidity of the soil were sent to the microcontrolador, and the supply of water in each sub-
areas it was accomplished with efficiency, in other words, in the sub-areas that the sensor ones
accused dry soil, the microcontrolador tied the bomb of water and when it accused humid soil,
separated the bomb, with that it was gotten to maintain in balance the amount of water supplied to the
soil.
