20.500.12556/RUL-186734 Merilnik kakovosti zraka v domačem okolju z oddaljenim dostopom na osnovi Raspberry Pi Raspberry Pi-based home air quality monitor with remote access Kakovost zraka v notranjih prostorih pomembno vpliva na zdravje in počutje vendar človek s svojimi čutili ne more zanesljivo oceniti vseh parametrov, ki jo določajo. V okviru diplomskega dela je bil zato razvit merilni sistem za spremljanje kakovosti zraka v domačem okolju. Sistem temelji na enoploščnem računalniku Raspberry Pi Zero 2 W in meri koncentracijo ogljikovega dioksida, temperaturo, relativno vlažnost, zračni tlak, osvetljenost ter koncentracijo delcev PM₂.₅ in PM₁₀. Meritve zajema v desetminutnih intervalih in jih shranjuje v lokalno podatkovno bazo SQLite. Trenutne vrednosti prikazuje na OLED prikazovalniku, pregled zgodovine in grafični prikaz meritev pa omogoča spletni uporabniški vmesnik. Delovanje izdelanega sistema je bilo ovrednoteno s primerjavo izmerjenih vrednosti z vrednostmi komercialnih merilnikov in z analizo odziva sistema na spremembe razmer v prostoru. Indoor air quality significantly affects human health and well-being. However, human senses cannot reliably assess all the parameters that determine it. Therefore, a measurement system for monitoring air quality in a residential environment was developed as part of this thesis. The system is based on a Raspberry Pi Zero 2 W single-board computer and measures carbon dioxide concentration, temperature, relative humidity, atmospheric pressure, illuminance, PM₂.₅ and PM₁₀ concentrations. Measurements are recorded at ten-minute intervals and stored in a local SQLite database. Current values are displayed on an OLED screen, while measurement history can be reviewed through a web-based user interface. The performance of the developed system was evaluated by comparing its readings with those obtained from commercial monitoring devices and by analysing its response to changes in indoor conditions. kakovost zraka v notranjih prostorih Raspberry Pi ogljikov dioksid prašni delci spletni uporabniški vmesnik indoor air quality Raspberry Pi carbon dioxide particulate matter web user interface true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-04 11:20:00 2026-09-04 11:20:09 2026-09-14 13:05:32 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63382 291020035 Legat_Matej_-_Merilnik_kakovosti_zraka_v_domacem_okolju_z_oddaljenim_dostopom_na_osnovi_Raspberr.pdf Legat_Matej_-_Merilnik_kakovosti_zraka_v_domacem_okolju_z_oddaljenim_dostopom_na_osnovi_Raspberr.pdf 1 9BB871C72B31C4E2D03099AA00DCB3AA 57be174110343108c74d539a40cfbf822b83bbfef1515a1b971ae96c421a75c4 d35f38fd-a841-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246079 Fakulteta za elektrotehniko 0 0 0
