20.500.12556/RUL-120153 Mobilni sistem za spremljanje temperature, vlage in kakovosti zraka Mobile system for temperature, humidity and air quality monitoring Cilj diplomske naloge je bil razvoj mobilnega sistema za spremljanje temperature, vlage in koncentracij plinov v različnih okoljih, kot so bivalni prostori in skladišča živil, kjer je potrebno zagotavljanje hladne verige. Razvit je bil prototip sistema, ki ga sestavljajo vozlišče s tipali za zajem meritev, strežnik s podatkovno bazo za shranjevanje podatkov in mobilna ter spletna aplikacija za povezavo z vozliščem in obdelavo podatkov. Vozlišče podpira tipala družine MQ za zaznavanje plinov, tipali DHT11 in DHT22 za temperaturo in vlago, modul za kartico SD in modul za brezžično povezavo z ESP8266, ki skrbi za pošiljanje podatkov na strežnik. Aplikaciji ponujata pregled in urejanje podatkov v človeku prijazni obliki. Merilni sistem je bil testiran v realnih pogojih za ugotavljanje izoliranosti hladilne skrinje in kakovosti zraka v sobi. V obeh primerih so tipala posredovala pričakovane rezultate in sistem je v celoti deloval brezhibno. The aim of the Bachelor thesis was the development of a mobile system for monitoring temperature, humidity and gas concentrations in various environments, such as living environments, food warehouses, where cold storage must be ensured. The developed prototype of the system consists of a node with sensors for capturing measurements, a server with the database for storing data, and a mobile and web application for connection to the node and for processing the data. The node supports MQ family sensors for measuring gases, DHT11 and DHT22 sensors for measuring temperature and humidity, an SD card module and a module for wireless connection with ESP8266 through which the data are sent to the server. The server is used to store the data and acts as an intermediate link between the applications and the node. The applications allow to review and edit the data on the server in a human-friendly form. The system was used in real conditions by testing the insulation of the cool box and measuring the air quality in the room. In both cases sensors provided expected results and system performed without an error. merilni sistem mikrokrmilnik STM32 tipala mobilna aplikacija kakovost zraka measuring system microcontroller STM32 sensors mobile application air quality true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-09-16 11:20:16 2020-09-16 11:20:20 2024-02-16 09:21:44 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 26143 32066563 Amon_Marko_-_Mobilni_sistem_za_spremljanje_temperature,_vlage_in_kakovosti_zraka.pdf Amon_Marko_-_Mobilni_sistem_za_spremljanje_temperature,_vlage_in_kakovosti_zraka.pdf 1 83D69582E96AE2E3DD2C63F5818CEBD3 852d2573dbfcc580b1d3e5743032fccfe53259f7c7e651a894e18226d30015a4 03042147-a1ba-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=134924 Fakulteta za računalništvo in informatiko 0 0 0
