Abstract
- Uređaji Interneta stvari (IoT-uređaji) koriste se u brojnim domenama zbog mogućnosti prikupljanja i odašiljanja podataka s različitih senzora. U domovima i zgradama se mogu koristiti za upravljanje osvjetljenjem, sustavima za grijanje i hlađenje i višemedijskim sustavima. Ovaj diplomski rad istražuje mogućnosti detekcije prisutnosti i praćenja broja osoba u prostoriji pomoću takvih uređaja. U okviru diplomskog rada istraženi su dostupni hardverski uređaji i mehanizmi za navedenu primjenu. Korištenjem PIR senzora, mikrokontrolera Waspmote, komunikacijskih modula XBee te senzorskih pločica postavljen je sustav za detekciju prisutnosti osoba u prostoriji. Također, razvijen je algoritam koji koristi podatke o prisutnosti sa senzora te vrši predviđanja o ukupnom broju ljudi u prostoriji. Na temelju stvarnih podataka o broju ljudi u prostoriji te podataka dobivenih algoritmom, izvršena je analiza performansi sustava u laboratorijskom okruženju. Internet of Things devices are used for various purposes because of their ability to collect and transmit data from various sensors. In homes and buildings, they can be used to control lighting, heating and cooling systems and multimedia systems. This thesis explores the possibilities of monitoring the number of people in the room and user presence detection by using IoT devices. Within this Master thesis, the available hardware devices and mechanisms for the mentioned domain were investigated. Using PIR sensors, Waspmote microcontrollers, XBee communication modules and sensor boards, a system for user presence detection was deployed. Furthermore, an algorithm that uses presence data from sensors and makes predictions about the total number of people in the room has been developed. Based on the actual number of people in the room and the data obtained by the algorithm, an analysis of the system performance was performed in the laboratory environment.
