ABSTRACT After developing technology in ultra-low power systems and sensors, a very good effort has grown on developing units capable to energy harvesting of limited power levels inherent to the surrounding environment. These energy species are vibrational, acoustic waves, temperature, e/m waves, motion and light sources. We can exploit those energies to turn in electric energy for powering modern sensors or sensor units, placed on anyinaccessible places.The device design we describe and explain on this paper is an energy harvester of light sources from electric lamps in closed rooms to sunlight. It’s based on a small photovoltaic panel (PV) of 100cm2and an MSP430F5529LP microcontroller (μC) board, responsible to track the direction of max light intensity and control two servo motors for moving the PV panel towards it. In addition, the μCderives maximum power from PV keeping the operation to Maximum Power Point (MPP). The device has a circuit to charge a battery, too, to keep powering the sensor unit during dark or very low-level lighting periods of a day. |
