Hybrid mobile application for viewing temperatures

Cilj diplomske naloge je bil razviti hibridno mobilno aplikacijo, ki uporabniku omogoča pregled podatkov izmerjenih iz temperaturnih senzorjev postavljenih po objektu. Poleg aplikacije se je razvil tudi zaledni sistem, ki preko API vmesnika shranjuje meritve temperaturnih senzorjev. Aplikacija je bila razvita z uporabo ogrodja Ionic, ki uporablja Angular in Apache Cordova za izgradnjo hibridne aplikacije. Uporabnik lahko do podatkov temperaturnih senzorjev dostopa na več različnih načinov, in sicer preko že obstoječe lokalne baze, neposredno z uporabo MQTT protokola in preko našega zalednega sistema. Zaledni sistem uporablja Docker-Compose za povezavo komponent zapakiranih znotraj Docker vsebnikov. Vsaka komponenta je realizirana s svojo tehnologijo glede na vlogo, ki jo opravlja. Node.Js je bi uporabljen za implementacijo API-ja, Eclipse Mosquitto kot MQTT posrednik, phpPgAdmin za hiter vpogled do baze in PostgreSQL za bazo. Diplomska naloga vpisuje tudi različne načine razvoja hibridnih aplikacij, navede njihove prednosti in slabosti ter jih med seboj primerja.The aim of the thesis was to develop a hybrid mobile application, which allows the user to monitor temperatures from sensors inside a building. In addition to the application, a back-end was developed. It is used for storing measurements sent from sensors via the API interface. The mobile application was built using the Ionic framework, which uses Angular and Apache Cordova to build hybrid mobile applications. It allows a user to access data from several databases, namely from a preexisting local database, direct connection to sensors using MQTT and from our own back-end database. The back-end is implemented with Docker-Compose, which connects all of the components packed up in Docker containers. Each container is implemented with different technology, depending on its role. Node.Js is used for API, Eclipse Mosquitto as an MQTT broker, phpPgAdmin for quick database access and PostgreSQL for a database. The thesis also describes different approaches to creating hybrid applications, shows their advantages and compares them
