Abstract

U ovom radu razmatrane su mogućnosti napajanja bežičnog senzorskog čvora energijom prikupljenom iz elektromagnetskog polja kabela te je odlučeno da će se koristiti električno polje kabela, odnosno kapacitivna veza. Dana je fizikalna podloga za rad te je potom ostvareno i sklopovsko rješenje sustava. Navedeni su i osnovni naputci za sklapanje osnovnih komponenata sustava u cjelinu. Na kraju je u praksi pokazano kako je vodljivom aluminijskom folijom duljine 83 cm, omotanom oko kabela, moguće prikupiti dovoljno energije za slanje podataka o temperaturi bežičnim senzorskim čvorom svakih 5 s. Daljnjim povećanjem duljine vodljive folije moguće je slati podatke u još kraćim vremenskim razmacima.

Abstract (english)

In this project the power options for a wireless sensor node using a cable electromagnetic field were scrutinized and it was decided that the electric cable field would be used, that is, capacitive coupling. Physical basis was given and a firmware solution of the system was achieved afterwards. Aditionally, basic instructions for the system components assembly are given in the text. At last it was shown that it is possible in practice, using an 83 cm long conductive aluminium foil wrapped around a cable, to harvest enough energy to transfer temperature data over the wireless sensor node every 5 seconds. Lengthening the foil makes it possible to transfer data in even shorter time periods.
