摘要: It is expected that the number of Internet Things (IoT) devices will grow significantly in coming years. Batteries, which are today most common source energy supply for these devices, have many limitations. The limited capacity and negative environmental effect their production recycling among crucial ones. Energy harvesting has been proposed to overcome this problem. Over past decade, academia produced thousands papers on topic, but it still difficult find a commercial sensor node operating solely with harvesting. One major reasons highly opportunistic unreliable nature income from available ambient sources. In paper, we address problem by proposing control loop enabling an request recharge whenever needed. Energy-wise, method effectively transforms operation mode passive wireless device proactive, thus application operate more predictable manner. feasibility efficiency approach demonstrated implementing real-life prototype Bluetooth Low capable equipped photovoltaic harvester, can communicate indoor smart lighting system.
