Abstract

Ovaj rad se bavio istraživanjem načina prijenosa podataka sa senzorskih čvorova korištenjem komunikacijskih tehnologija XBee, Bluetooth Low Energy, LoRaWAN i WiFi. Komunikacija je ostvarena pomoću uređaja Waspmote. Waspmote je bežična senzorska platforma koja s niskom energetskom potrošnjom omogućuje da senzorski čvorovi samostalno šalju radio signale. Na Waspmote moguće je priključiti senzore, antene, komunikacijske module ili druge senzorske pločice. Waspmote ima različite načine rada,i svaki način rada je energetsko stanje u kojem Waspmote troši određenu energiju. Najviše energije se troši dok Waspmote šalje signale odnosno dok je uključen, a najmanje dok je u stanju spavanja. Od četiri zadane tehnologije, ona s najmanjom energetskom potrošnjom je Bluetooth Low Energy. Zadatak je bio ostvariti komunikaciju prethodno navedenim tehnologijama. Za realizaciju svake tehnologije potrebna su po dva modula i jedan ili dva Waspmote uređaja, ovisno o tehnologiji. Jedan modul se ponaša kao odašiljač signala, a drugi kao prijemnik. Module je potrebno podesiti na jednake parametre da bi mogli komunicirati. Podatci koji su se slali između odašiljača i prijemnika su vrijednosti temperature očitane sa senzora. Osim ovog, na početku rada obrađena je tema Interneta Stvari. Internet Stvari definiramo kao veliki broj umreženih heterogenih uređaja koji su okruženi pametnom okolinom. Takav skup uređaja prikuplja, obrađuje, pohranjuje i prenosi podatke i informacije.

Abstract (english)

This thesis research covers the multiple ways to send data from sensor node using XBee, Bluetooth Low Energy, LoRaWAN and WiFi communication technologies. Communication between two nodes is established using Waspmote devices. Waspmote is wireless sensor platform with low energy consumption, which enables nodes to send data independently. Different modules, sensors, antennas and other sensors can be connected to the board. Waspmote uses different modes of operation with corresponding energy consumption. The highest energy consumption is when Waspmote is turned on and sending signals, while the lowest is during sleep mode. Out of the four used technologies, Bluetooth Low Energy technology has the lowest consumption of energy. The main task was to establish communication with previous mentioned technologies. In order to establish communication, two modules od each technology are required and one or two Waspmotes, depending on the used technology. One module acts as a sender and the other as the receiver. They need to be set up with the same parameters in order for them to communicate. Data sent between sender and receiver are values read from temperature sensors. The thesis also covers IoT research. We define IoT (Internet of Things) as great number of connected nodes in a smart environment. This convention of devices collects, handles, stores and sends data and information.
