This paper presents an overview of the Internet of Things (IoT) device design and simulation, explicitly focusing on low-power design principles. Everything in the context of a European project. Our key motivations include reducing economic costs, minimizing battery replacements or recharges, and mitigating environmental impacts. The primary focus is on a custom IoT localization tag, for which we simulate solar cells (i.e., from basic modeling to their integration into electrical circuits) and the power consumption of the tag's electronics platform. The analyzed sample platform is built on the nRF52833 and the DW3110 ultra-wideband controller. We also used the principles of the DYNAMIC, our experimental framework, to optimize power consumption and extend battery life.
Reductions in photovoltaic panel area were achieved for both devices with a 5-year lifespan and fully autonomous systems, though with increased localization latency. Our results also demonstrate how IoT devices, including their simple firmware, can be effectively simulated using publicly available tools.
