Design and Implementation of Solar Energy Harvesting with Double Booster Circuit in Wireless Sensor Networks

Non-conventional sources of energy have gained a lot of interest in the past few decades. Low power applications including embedded systems and wireless sensor network are being explored for energy harvesting from external sources. The abundant source of energy i.e., solar energy is widely used because of its high output and conversion efficiency than other sources like RF energy, piezoelectricity, thermal energy, etc. The harvested power in terms of some microwatts or milliwatts is used to supply in low power applications. In this paper, a solar energy harvesting circuit design is presented with an enhancement of the double booster circuit that increases the output power. The double booster circuit comprises voltage and current booster circuit. The implemented circuit boosts the power to 0.5-1.5 watts depending upon the duration of time. Solar Energy harvesting can be viewed as potential source for extending lifetime of the wireless sensor network.
