Abstract
Real-time monitoring provides reliable, timely information of crop and soil status, important in
taking decisions for crop production improvement. The contribution of this research is the development
of a real-time remote monitoring system that acquires data from any kind of sensor to be transmitted
by radiofrequency to puter with an interface module, situated within a 900 m radius. This
allows the sensing of large area fields with a system capable of monitoring crop local environmental
or physiological status; the data transmission and storage in puter is made in real-time. To
design this device, the system on a chip approach was followed. Implementation was done in a field
programmable gate array, which ensures a low cost. The performance of this system was tested
using different kinds of sensors pared with mercial monitoring systems under
greenhouse conditions. The experimental results showed the system to be reliable. For all experiments,
the system obtained an R2 greater than or equal in a regression analysis between data acquired
from our monitoring system and data obtained from mercial datalogger with linear fit and
second-degree polynomial fit.
