A module harvesting wind and solar energy for wireless sensor node

Abstract

This paper makes an introduction to a module harvesting wind and solar, it is designed for wireless sensor node to meet the need of power in outdoor application like forest monitoring. To get very long life, the module harvests wind and solar together, takes the super capacitor and alternate lithium battery as the energy store device to take advantage of their complementary nature. A wind MPPT (maximum power point tracking) circuit which is specifically designed for application in wireless sensor network and a solar tracking circuit are designed to increase the efficiency of energy harvesting. © 2013 Springer-Verlag.
