| Sumario: | The main objective of this project is to validate the nanosatellites as a technology for crop monitoring. In order to validate the technology, the idea is to design and build a preliminary prototype for a proof of concept, receiving data from a crop and processing it so it can be transmitted to a nanosatellite. To contextualize the proof of concept, the first step was to do a selection of crops of interest and parameters to measure. After comparing data and considering many high production crops, soy and tomato were chosen. Both are produced in big quantities and in different parts from both northern and southern hemisphere. This is an interesting fact, because the nanosatellites can be used during more time through the year. Regarding the parameters, temperature and humidity were chosen. The proof of concept consists in building a prototype with three sensors, able to transmit measurements to a nanosatellite. A sensor to measure soil temperature (THERM200), a sensor to measure soil humidity (VH400) and a sensor to measure both air temperature and air humidity (DHT22) were chosen. This three sensors connect to a microcontroller (Arduino Uno), which processes the measurements and prepare them to be transmitted. The measurements are sent to the nanosatellites through a terminal using the KISS (Keep It Simle, Stupid!) protocol. A prototype that receives and stores the measurements from the sensors was successfully built. The measurements are stored in KISS frames with the smallest possible size. Due to exceptional circumstances, it was not possible to have access to nanosattelites. For that reason, the communication was tested between two "terrestrial" nodes". Communication with nanosatellites is pending to be verified. The prototype is functional and ready for when is possible to access to nanosatellites. Although the commnication with nanosatellites was not assessed, which is an important part of the study, the work in selecting crops, building the prototype, gathering data and transmitting the information was done successfully. |
