APPLICATION FOR COLLECTION AND ANALYSIS OF AIR QUALITY DATA

U ovom radu biti će opisan razvoj web aplikacije za kontrolu kvalitete zraka. OdreĎeno je 5 mjernih točaka u gradu Splitu prema kojima će se podaci prikazati tablično i grafički. Vrijednosti koje se mjere su temperatura, vlaga te postotoak vlage u zraku. Aplikacija ―Air Quality Control‖ izraĎena je u JavaScript programskom jeziku, HTML prezentacijskom jeziku te CSS stilskom jeziku. Za izradu sučelja aplikacije korištena je kombinacija nekoliko JavaScript biblioteka od kojih treba posebno izdvojiti React te MaterialUI biblioteke. Pozadinski servis temeljen je na Express aplikacijskom okruţenju i Node.js okruţenju za vrijeme izvoĎenja. Za pohranu podataka korišten je MongoDB program baze podataka. Tehnologije MongoDB, Express, React te Node.js zajedno čine takozvani MERN stog. Mjerenja koja su se koristila u izradi ovog rada svojom strukturom temelje se na mjerenjima kolege Ante Botice u njegovom završnom radu ―Beţična senzorska mreţa za mjerenje kvalitete zraka‖.This paper will describe the development of a web application for air quality control. 5 measuring points in the city of Split have been determined, according to which the data will be presented tabularly and graphically. The values that are measured are temperature, humidity and the percentage of moisture in the air. "Air Quality Control" application is created in JavaScript programming language, HTML presentation language and CSS style language. A combination of several JavaScript libraries was used to create the application interface, of which React and MaterialUI libraries should be singled out. The backend service is based on the Express application environment and the Node.js runtime environment. The MongoDB database program was used for data storage. Technologies MongoDB, Express, React and Node.js together form the so-called MERN stack. The measurements that were used in the creation of this work are based on the measurements of my colleague Ante Botica in his final work "Wireless sensor network for measuring air quality"
