Sažetak
Networks of underwater sensors are used in watercourses for measuring and wirelessly transmitting, among others, pollution levels. To ensure constant work, each sensor node requires a power source. In this frame, energy harvesting devices based on miniaturized hydro-generators appear a viable autonomous powering option whose concept is described in this work. The harvester is based on a DC generator and a 3D printed propeller driven by the river flow. A suitable energy management electronics is also developed. Measurements on the innovative hydro-generator are carried on in real-life river conditions, as well as in a flow tunnel. The measured generated power levels correspond to values needed to constantly power a sensor node.
