Abstract

Sensing networks have recently proven to be useful in a variety of disciplines. The use of mobile sensing robots and unmanned aerial vehicles (UAVs) is intended to lessen the burden of sensor node energy consumption. However, conserving energy in the networks remains a major concern. In this work, a design of a hybrid RF-Solar harvesting system to support sensing devices is investigated. The harvesting circuits may collect energy from both solar and radio frequency (RF) resources that are commonly available in ambient environments. This approach creates hybrid harvesting circuits for all elements in the combined sensor networks by combining RF and solar harvester circuits. The RF harvester circuit is a dual-band multi-stage harvester for the 2.4GHz Wi-Fi/WLAN spectrum. In the solo solar harvester circuit, a solar panel with a maximum power point tracking (MPPT) algorithm is employed. The hybrid system can offer a maximum power of up to 136.5W due to a boost current element in the charging system. Because each node has a rechargeable battery, the gathered power from the proposed circuits is used to charge all of the batteries. This strategy allows networks to run safely and continuously even when there is a scarcity of gathered electricity due to severe weather, as cloudy or rainy days. This work is both promising and practical.
