Analysis of energy harvesters for powering a wireless sensor node device

Abstract

This study analyses energy harvesters used to power a wireless sensor node. The sensor node measures the ambient temperature and transmits the data to a coordinator. Three main energy sources are investigated: solar, radio frequency and thermal. The energy produced by these devices is investigated under various environmental conditions to ensure that it can reliably supply the required amount of power to the wireless sensor node. The results show that these energy sources can provide power to the wireless sensor node at different transmission rates with an average power of 0.16 W during each data transmission.
