Laburpena: gradu amaierako lan honen helburua sare sentsore inalanbrikoa egitea da. Hori egiteko DHT11 sentsorea aukeratu da eta horrekin egin ahal izango da eguraldi simulazioa. Honekin tenperatura eta hezetasunari buruzko informazioa jasotzen da, geroago monitoreetara bidaltzeko. Komunikazio inalanbrikoa egin ahal izateko, irrati frekuentzia moduluak erabili dira, zehazki 433mhz. Honek komunikazio erreza ahalbidetzen du hartzaile eta bidaltzailearen artean. Moduluaren antenarekin distantzia normala izan daiteke, nahikoa gure sistemaren komunikazioa mantentzeko, baina badaezpada posiblea da ipintzea antena berezi bat distantzia gehiago izateko. Energia berriztagarriei esker eta sistemaren hornikuntza propioari esker gai da modu autonomo eta independente batean funtzionatzeko. Hori gainditzeko energia hartu behar du nonahi. Horretarako inplementatu da eguzki plaka bat, honekin sistema edonon ipintzeko errazago izango da. Eguzkitik hartutako izpiak transformatu behar dira. Energia hori aldatzeko, zirkuito BOOST erabiltzen da, kasu honetan energia handitu beharko da. Datuak jasotzeko Arduino plakak erabiliko dira. Nola plaka asko dauden aukeratzeko, hartu dira sistemaren arabera hobeto moldatzen direnak. Gradu Amaierako lan honen bidez posiblea da ahalik eta azkarren komunikatzea nodoen artean, datuak jaso eta taula batean gorde. Nodoekin jasotako datu guztiak zerbitzari batera bidali ahal izango dira. Horrela langile guztiak kontsultatu ahal izango dute interneten bidez
Abstract: through this final grade project it is intended to perform a wireless network by some sensors simulating a weather station. It has been used a DHT11 sensor for do this. DHT11 allows to collection temperature and humidity data. To make the wireless communication have been used radio frequency modules, specifically of 433mhz. These modules allow easy communication between sender and receiver. These modules does not reach great distances because are prepared for simple jobs. If the antenna is modified, it will have more reach. For reasons of demand for renewable energies and thinking about self-feeding system. This project can work independently and autonomous. Has been implemented a solar panel for power the circuit. This characteristics make possible to place the nodes anywhere as long as the antenna allow it. The energy we can collect it is transformed in order to power the system. To make this possible we use DC-DC boost circuit. We make the data collection with Arduino cards, specifically NANO cards, because it is the best option for the needs of the system. The purpose of this project is to be able to act directly and faster on the node. To enable this, all the data collection from temperature and humidity are download on a spreadsheet or uploaded to the server cloud.
Resumen: se trata de una red inalámbrica de sensores mediante módulos de radiofrecuencia, donde la adquisición y toma de medidas y resultados se realiza a través de varias plataformas de visualización. Como pueden ser: Labview, servidor LAMP mediante tarjeta Raspberry pi, aplicación móvil, pantalla LCD.
