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.

• Title: Mobile system for temperature, humidity and air quality monitoring

Abstract

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.
