This research presents the design and implementation of a precision agriculture system using sensor networks as the basis in precision agriculture for farmers of white cabbage (Brassica rapa ssp. Pekinensis) in Panama/China with the aim of transferring knowledge and mitigating the effects of the soil and climate change on crops of white cabbage. Finally we found the optimal ranges to improve productivity and avoid losses due to uncontrolled agroclimatic variables such as relative temperature, soil temperature, relative humidity, soil moisture and luminosity.
