  7. 5. Storage System for Harvested Energy in IoT Sensors

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Saif Alhuttaitawi; [2018]
    Nyckelord :Renewable energy; power management; energy harvesting; energy storage; super capacitor;

    Sammanfattning : This work presents an energy system design for wireless sensor networks (WSNs) after applying our design the WSN should theoretically have an infinite lifetime. Energy harvesting sources can provide suitable energy for WSN nodes and reduce their dependence on battery. In this project, an efficient energy harvesting and storage system is proposed. LÄS MER
