Descrição:This project presents the implementation of a data acquisition systembased on Internet of Things (IoT) technology and low-cost electronicmicrocontrollers for measuring structural strains. The system hardwarewas integrated using a quarter-bridge strain gauge, a strain measurementmodule, an Arduino Uno, and a Raspberry Pi, along with several softwaretools, including Cayenne, to enable IoT connectivity. The resultingsystem allows real-time acquisition, visualization, and storage of strainmeasurement data. The performance of the electronic system wasvalidated by monitoring strains at two locations on a cantileverstructural specimen subjected to stepwise load increments at its free end.Experimental results were compared with analytical values calculatedusing Euler-Bernoulli beam theory, yielding a maximum difference of 5%relative to theoretical predictions.
