Precision agriculture can be defined as the science of using technology to improve the
agricultural production. It is advisable for farmers to use a decision support system; in fact, real–
time monitoring of climatic conditions is the only way to know the water needed by a cultivation.
On the other hand, since the 1990s, a strong decrease of the Mediterranean Quercus has been observed
in the pastures of southwestern Spain and Portugal, causing a high mortality of holm and cork oak
trees. Among the factors associated with this decrease, the radical decomposition caused by
Phytophthora Cinnamomi is remarkable for its gravity, which makes it necessary to reforest the trees
and to monitor the microclimatic factors that have an influence on this regeneration. Wireless Sensor
Networks (WSN) are a technology in full evolution and development, as well as their appropriate
use in cultivations that help to implement ecological techniques. With these considerations in this
work five units/nodes with one or more sensors that allow different environmental readings have
been developed. In this work, the acquisition of data obtained from different sensors has been
achieved, allowing the monitoring of climatic elements such as soil moisture, air quality,
temperature and humidity, rainfall intensity, precipitation level, wind speed and direction,
luminous flux and atmospheric pressure. A web page has been designed where the user can consult
the climatic conditions of the cultivation or reforestation. Different devices interconnected with a
central unit have been developed where measurements of the cultivation are sent for its later
analysis by the farmer. The microclimatic data acquisition developed in the WSN proposed in this
paper allows a farmer to make decisions about the irrigation of the cultivation, use of fertilizers, the
development and maturation phases of the cultivated products, obtaining the optimum stages of
cultivation and harvesting.
