Development of an Infrared Sensor for the Detection of Falling Product in Vending Machines

U ovom radu opisana je izrada infracrvenog senzora za detekciju prolaska objekta uporabom programskog alata Altium Designer i programskog jezika C. Izrada počinje dizajnom električne sheme, izborom komponenata i projektiranjem tiskane pločice. Nakon toga se piše programska potpora te se obavlja testiranje, u sklopu čega je predložena konstrukcija testnog okruženja. Rezultat rada je funkcionalan infracrveni senzor prolaska koji je otporan na istosmjerne smetnje. U radu je razmotrena i ukomponirana opcija snimanja 2D slike predmeta detektiranog senzorom i predložene su moguće nadogradnje.This Master’s thesis describes the development of the infra-red sensor for motion detection using Altium Designer and C programing language. The development begins with the design of the electrical scheme, the selection of components, and the design of the printed circuit board. Afterward, the firmware is written and testing is carried out, as pas part of which the construction of the test environment is proposed. The result is a functional infrared motion sensor resistant to DC interference. In the thesis, the option of recording a 2D image of the object detected by the sensor was considered and integrated, and possible upgrades were proposed
