Abstract

Sustav koji se sastoji od senzora za mjerenje temperature, poslužiteljskog računala i mobilne aplikacije. Senzor je ugradbeni računalni sustav koji očitava temperaturu s najviše 3 povezana termistora mjerenjem otpora. Poslužiteljsko računalo prima očitanja i sprema ih u bazu podataka te komunicira s mobilnom aplikacijom. Mobilna aplikacija prikazuje trenutna mjerenja i omogućuje dodavanje novih uređaja. Očitanja se šalju MQTT protokolom, a mobilna aplikacija komunicira HTTP protokolom i REST API sučeljem.

Abstract (english)

A system that consists of a sensor for measuring temperature, a server and a mobile application. The sensor is a embedded computer system that measures the temperature from at most 3 connected thermistors by measuring their resistance. The server receives the measurements and stores them in a database and responds to requests from the mobile application. The mobile application displays current temperature readings and enables the addition of new devices. The readings are being transmitted using the MQTT protocol and the mobile app communicates using the HTTP protocol and REST API interface.
