|a Sažetak na hrvatskom: Upravljajući grijačem termokomore, zadatak rada je postaviti i održati temperaturu na zadanoj veličini. Čitav sustav se sastoji od osjetila temperature, upravljačkog sklopa i pogonskog sklopa grijača. Za upravljački sklop odabran je mikrokontroler Arduino Uno, a za senzore Dallasovi DS18B20 kao komponente već na raspolaganju. Regulatori bi se ostvarili razvojem programske podrške za mikrokontroler.
Za početak čitav sustav se testirao na maketi termokomore, koja je bila napravljena od stiropora i aluminijske folije kao termičkih izolatora, da bi se potvrdio rad dvaju regulatora, proporcionalnog pojačanja i relejnog regulatora. Snaga, iako mala, je bila dovoljna da reprezentira jedan sustav na kojem se dalo izvesti mjerenja i usavršiti regulatore. Tako se nakon rada na maketi termokomore rad nastavio na grijaču snage 0,8 kW. Kroz mjerenja se pokazalo da je to dovoljno da se ispitaju temperature do 80 °C ali da se može ići i iznad 100 °C. Postignuti su prvi ciljevi da se uklone nadvišenja, te da temperatura može ostati unutar željenih granica kombinacijom oba regulatora. Sva programska podrška pisana je i koristi se na Arduino Uno mikrokontroleru, kojeg smo uklopili i na tiskanu pločicu koju smo izradili posebno za potrebe pogonskog i upravljačkog sklopa. Osim programiranja za Arduino skriptom u Matlabu se prikupljalo podatke radi lakše kasnije obrade, a u KiCadu se napravila tiskana pločica.

|a Sažetak na engleskom: Controlling the heater, the goal of this paper is to set and maintain temperature on a referent value. The whole system consists of a temperature sensor, controlling set, and a heating drive. Microcontroller Arduino Uno was chosen for the controlling set, and for the temperature sensors where used Dallas DS18B20, as off-the-shelf components. Regulators would be achieved developing program support for the microcontroller.
In the beginning the whole system was tested on a model of a thermal chamber made out of aluminium foil and styrofoam as thermal insulators, so the effectiveness of the two chosen regulators could be confirmed, the proportional gain regulator and relay regulator. Although the power of the model was small, it was enough to demonstrate one system on which measurements could be made. The work was continued on a much bigger thermal chamber with the power of 0,8 kW. Temperatures that could be achieved where around 80 °C but could also go a little above 100 °C. First goals where reached and systems overshoot was taken care of, and the measured temperature was staying inside tolerated temperature values. Software developed was written and used on the Arduino Uno microcontroller which was integrated with the PCB developed for the system. Besides programming for Arduino, a script was used in Matlab to collect data, and for easier processing and interpretation od the data. The PCB was developed in an open source program called KiCad.
