U sklopu ovog završnog rada osmišljena je i implementirana usluga detekcije požara primjenom IoT uređaja. Usluga koja je razvijena sastoji se od MQ2 senzora povezanog s ESP32 mikrokontrolerom. Podaci očitani na mikrokontroleru, a prikupljeni sa senzora, dostavljaju se internetom uz pomoć MQTT protokola na server stranu web aplikacije. Primljeni podaci se prikazuju, obrađuju i pohranjuju u web aplikaciji razvijenoj u tehnologijama Spring Boot, Thymeleaf i PostgreSQL. U radu je opisan ciklus razvoja - razrada problema, izbor tehnologija, implementacija usluge i demonstracijsko korištenje. This thesis is based on the design and implementation of a fire detection service using an IoT device. The designed service is comprised of an MQ2 sensor connected to an ESP32 micro-controller. Data gathered by the sensor is processed on the micro-controller and is then transmitted using the MQTT protocol to the web application server. Received data is then shown, processed and stored in the web application built using Spring Boot, Thymeleaf and PostgreSQL technologies. This thesis paper describes the entirety of the service development cycle, including the problem elaboration, technology choice, service implementation and demonstration of use. |
