Optimización del sistema de caracterización de parámetros climáticos en mini jardines clónales forestales bajo ambiente protegido.
Abstract
This document describes the process of research and optimization of the
system for characterization of weather parameters in mini clonal forest gardens
under controlled environment conditions implemented at a GENFORES2
green
house located in Santa Clara, in the Costa Rica Institute of Technology. With the
implementation of the project, it will be able to send the recollected information
from the sensors through the nodes and upload it to internet.
The procedures for the implementation of the project were based on a first
assessment of the case done in the location to diagnose the main deficiencies of
the employed system one year ago. The results identified the need to implement
changes to find a different way to transport the information from the base node to
the user access point. For this reason, the architecture of the network was
redesigned using a Beaglebone to control a USB modem, which allows the internet
access through third generation technology. The I2C communications protocol was
used to transmit information between the base node and the Beaglebone. Also, it
was necessary to add an additional module of lighting, which allows the extending
of the plants’ photoperiod as part of the GENFORES experiments.
The optimizations implemented in the software routines allowed to reach the
requirements in the decrease of current consume to avoid overheating on the base
node. All the reached objectives are important because their contribution with the
GENFORES team labor to ensure the improvement and development of forest
genetic resources
