Abstract(s)
Com os diversos avanços verificados nas tecnologias de redes sensores sem fios, surge a
necessidade destes sistemas tornarem energeticamente autónomos. Historicamente, as
baterias têm sido as fontes de alimentação usadas para fornecer energia nestas
tecnologias. Visando solucionar as limitações apresentadas pelas baterias, inúmeras
pesquisas têm sido feitas para maximizar a vida útil e a capacidade dos nós sensores. As
técnicas de Energy Harvesting surgem com uma das soluções alternativa.
Esta dissertação tem como principal objetivo desenvolver um setup experimental, tendo
em vista recolha de energia através de um transdutor termoelétrico, utilizando a
diferença de temperatura entre a água de uma canalização, e a temperatura de um
material de mudança de fase que armazena energia solar térmica. A energia produzida
tem como objetivo de alimentar nós sensores usados na área de monitoramento de
distribuição de água. O sistema desenvolvido é composto por uma célula de Peltier, 2
termopares e ThermoBooster Pack acoplado ao Lanch Pad, sensor de corrente INA219,
microcontrolador mbed e o software de programação node-red. De maneira elevar a
energia produzida célula de Peltier e efetuar a sua regulação foi usado o conversor
LTC3108 da Linear Technology. Este circuito eletrónico faz parte do kit Energy
Harvesting Multi-Source Demo Board with Transducers DC2080A.
With the various advancements seen in wireless sensor network technologies, this systems need for energy autonomy. Normaly, batteries have been the power sources used to provide energy in these technologies. To solve the limitations presented by batteries, several researches have been proposed to maximize the lifetime and capacity of sensor nodes. Energy harvesting as na alterntive to power sensor nodes. This dissertation aims to develop an experimental setup, for energy harvesting from a thermoelectric transducer, using the difference temperature between the pipe water, and the temperature of a material that stores solar thermal energy. The energy produced will be used to power smart sensor. The experimental system consists of a Peltier cell, 2 thermocouples and ThermoBooster Pack coupled to the Lanch Pad, INA219 current sensor, mbed microcontroller and the software node-red. The Energy Harvesting (EH) Multi-Source Demo Board with Transducers DC2080A kit was used to regulate the energy produced by the Peltier cell.
