POWER SUPPLY APPARATUS FOR SMART SENSOR-NODE USING ENERGY HARVESTING

摘要

PURPOSE: A power supply device of a smart sensor node using energy harvesting is provided to maximize generation efficiency by minimizing air resistance to increase rotation efficiency of a rotator. CONSTITUTION: A sensor node(10) collects data and transmits collected data. A secondary battery(20) is embedded in the sensor node. An energy harvesting module(40) generates power from wind, water, and vibration energy. A charging module(30) receives power from the energy harvesting module and a photovoltaic power generation module. The charging module supplies the charged power to the secondary battery of the sensor node.
