20.500.12556/DKUM-97768 Design and implementation of an Arduino-based temperature monitoring system Bachelor's thesis Načrtovanje in implementacija sistema za spremljanje temperature na osnovi platforme Arduino diplomsko delo Diplomsko delo je osredotočeno na razvoj nizkocenovnega sistema za spremljanje temperature na osnovi mikrokrmilnika Arduino Uno. Glavni namen projekta je bil zasnovati, sestaviti in preizkusiti kompakten in cenovno dostopen sistem za merjenje temperature okolja, sproten prikaz izmerjenih vrednosti ter njihovo shranjevanje za nadaljnjo analizo. Sistem vključuje ploščo Arduino Uno, temperaturni senzor DHT11, modul za realni čas DS3231, LCD-zaslon 16x2 in bralnik kartic microSD. Programska oprema je bila razvita v okolju Arduino IDE z uporabo več knjižnic za komunikacijo s priključenimi moduli. Izmerjeni temperaturni podatki skupaj z datumom in časom so prikazani na LCD-zaslonu ter shranjeni v obliki CSV, kar omogoča kasnejšo obdelavo v programu Excel. Naloga vsebuje tudi pregled sodobnih metod merjenja temperature, vključno s termočleni, RTD-senzorji, infrardečimi temperaturnimi senzorji in digitalnimi temperaturnimi senzorji. Poleg tega obravnava možnosti shranjevanja in vizualizacije podatkov, kot so SD-kartica, Bluetooth in Wi-Fi moduli. Razviti sistem je bil preizkušen v realnih pogojih med 24-urnim eksperimentom. Dobljeni rezultati so bili primerjani z uradnimi podatki meteorološke postaje v Ptuju. Čeprav so bile opažene nekatere razlike v absolutnih temperaturnih vrednostih, predvsem zaradi različne postavitve senzorja in vpliva okolja, so grafi pokazali podoben trend spreminjanja temperature. To potrjuje, da je razviti sistem primeren za izobraževalne namene in za enostavne naloge dolgoročnega lokalnega spremljanja. Med možnimi izboljšavami v prihodnosti so boljša zaščita pred sončnim sevanjem, uporaba OLED-zaslona, brezžični prenos podatkov prek Wi-Fi in napajanje s sončno energijo za avtonomno delovanje. This diploma thesis is focused on the development of a low-cost temperature monitoring system based on the Arduino Uno microcontroller. The main purpose of the project was to design, assemble, and test a compact and affordable system for measuring ambient temperature, displaying the measured values in real time, and storing them for further analysis. The system includes an Arduino Uno board, a DHT11 temperature sensor, a DS3231 real-time clock module, a 16x2 LCD display, and a microSD card reader. The software was developed in Arduino IDE with the use of several libraries for communication with the connected modules. The measured temperature data together with date and time are displayed on the LCD and saved in CSV format, which allows later processing in Excel. The thesis also provides a literature review of modern temperature measurement methods, including thermocouples, RTD sensors, infrared temperature sensors, and digital temperature sensors. In addition, it discusses data storage and visualization options such as SD card, Bluetooth, and Wi-Fi modules. The developed system was tested in real conditions during a 24-hour experiment. The obtained results were compared with official meteorological station data from Ptuj. Although some differences in absolute temperature values were observed, mainly due to different sensor placement and environmental influences, the graphs showed similar temperature trends. This confirms that the developed system is suitable for educational purposes and for simple long-term local monitoring tasks. Future improvements may include better protection from solar radiation, the use of an OLED display, Wi-Fi data transmission, and solar power supply for autonomous operation.
