20.500.12556/RUL-188494 Načrtovanje in razvoj avtonomne, energijsko samozadostne pametne boje Design and Development of an Autonomous, Energy-Self-Sufficient Smart Buoy Cilj diplomskega dela je bil razviti pametno merilno bojo za spremljanje kakovosti vode, ki deluje čim bolj samooskrbno ter omogoča zanesljivo pošiljanje natančnih podatkov v realnem času. Za doseganje dolgotrajnega delovanja brez pogostih posegov uporabnika je bil sistem zasnovan z uporabo sončnih panelov za polnjenje baterij in funkcije globokega spanja (deep sleep) mikrokrmilnika ESP, s čimer se je bistveno zmanjšala poraba energije. Dodatno k nizki porabi prispeva uporaba komunikacijskega protokola LoRa, ki je energijsko učinkovitejši od tehnologij, kot so Wi-Fi, LTE in Bluetooth. Natančnost meritev je bila preverjena z validacijo uporabljenih senzorjev. pH-senzor je bil umerjen in preizkušen z referenčnimi pufrskimi raztopinami znanih vrednosti, rezultate pa smo dodatno primerjali z meritvami, pridobljenimi z indikatorskimi lističi. Meritve temperature vode so bile primerjane z referenčnim termometrom. Rezultati potrjujejo, da razvita boja omogoča energijsko učinkovito, zanesljivo in dovolj natančno spremljanje kakovosti vode, zato predstavlja primerno rešitev za dolgotrajni monitoring vodnih okolij. The aim of this thesis was to develop a smart monitoring buoy for water quality assessment that operates as autonomously as possible while enabling the reliable transmission of accurate data in real time. To achieve long-term operation without frequent user intervention, the system was designed to use solar panels for battery charging and the deep-sleep function of the ESP microcontroller, thereby significantly reducing energy consumption. The use of the LoRa communication protocol further contributes to low power consumption, as it is more energy-efficient than technologies such as Wi-Fi, LTE, and Bluetooth. Measurement accuracy was assessed by validating the sensors used in the system. The pH sensor was calibrated and tested using reference buffer solutions with known pH values, and the results were additionally compared with measurements obtained using pH indicator strips. Water temperature measurements were compared with those of a reference thermometer. The results confirm that the developed buoy enables energyefficient, reliable, and sufficiently accurate water quality monitoring, making it a suitable solution for the long-term monitoring of aquatic environments. pametna boja IoT LoRa kvaliteta vode smart buoy IoT water quality LoRa true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-23 13:45:01 2026-09-23 13:45:07 2026-09-24 04:25:31 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 38750 Mramor_Domen_-_Nacrtovanje_in_razvoj_avtonomne,_energijsko_samozadostne_pametne_boje.pdf Mramor_Domen_-_Nacrtovanje_in_razvoj_avtonomne,_energijsko_samozadostne_pametne_boje.pdf 1 9149A12FA3B8516B354B1BDDFA4A3039 c389d67a29099d8cce2d2b84a2d5d11219bf0b39cdac08872fc28747f3a9c66d 2cfcb378-b744-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=248681 Fakulteta za računalništvo in informatiko 0 0 0
