Abstract:

The growing demand for Internet of Things (IoT) devices is accompanied by a technological need for efficient batteries to ensure the flexibility of these wireless systems. In this work, an IoT device was developed to be powered exclusively by an energy harvesting system with a capacitor as its source of energy accumulation. This technique aims to collect the energy of the medium in which the device is located, such as: solar, kinetic, thermal, and radio frequency among others. Consequently, an efficient management of the energy required for data collection, communication and other tasks is a must. In this scenario, an efficient wireless micro-controller was selected for its low power consumption and multi-protocol integrated radio. An IoT device was then designed to operate without cables or batteries. Operation measurement results demonstrated its ability to perform 499 reads, writes and transmissions over 20 days without the need for additional recharge, making a purely capacitor supply operation feasible.
