Microgrids are localized, independent power grids that can operate while connected to the larger electrical grid. These systems make intelligent decisions regarding power management and use an array of components to monitor power generation, consumption, and environmental conditions. While this technology can save money, complex installation and maintenance has limited the adoption of microgrids in residential spaces. To simplify this technology, the next evolution of microgrid components includes sensors that are wireless and ambiently powered. Energy harvesting circuits can be incorporated into microgrid sensors, enabling them to recapture otherwise wasted environmental energy. Equipping microgrid sensors with energy harvesters simplifies the end user experience by eliminating the need for cable routing. Implementing energy harvesting techniques results in a microgrid that is easier to deploy, cleaner, and requires less maintenance. In this poster, we share the design, implementation, and evaluation of a hybrid energy harvesting and battery-powered sensor. We assessed the sensor’s performance through experiments, demonstrating its potential to operate autonomously and reliably for a decade or more without maintenance.
