Abstract

Prikupljanje energije (eng. energy harvesting) se koristi za produljenje radnog vijeka bežičnih senzorskih čvorova. U ovome radu zadatak je dizajn sklopa za prikupljanje sunčeve energije. Dizajnirani sklop omogućuje pretvorbu sunčeve energije u električnu energiju korištenu za punjenje kondenzatora. U slučaju nemogućnosti prikupljanja sunčeve energije dizajnirani sklop omogućiti napajanje senzorskog čvora iz baterije. Proučeno je aktualno stanje tehnologije i odabrati optimalni solarni panel za zadanu aplikaciju. Sklop je dizajniran u KiCadu i izveden na tiskanoj pločici dimenzija 5cm x 5cm.. Dizajniranom sklopu je nakon sastavljanja ispitana funkcionalnost i daljnja primjena.

Abstract (english)

Energy harvesting is used to extend the battery life of wireless sensor nodes. The task of this project was to design a circuit that is capable of collecting solar energy. The circuit is used for the conversion of solar into electrical energy, which will be used to charge a capacitor. In situations when solar energy harvesting is not efficient enough, the circuit provides power from a non-rechargeable battery. An optimal solar panel for the given application has been selected after examining the state-of-the-art. The circuit was designed in KiCad on a 5 cm x 5 cm PCB. The circuits functionality has been tested after assembly.
