ABSTRACT
Structural Health Monitoring (SHM) can be used to evaluate the condition of the structure’s integrity, or so far to verify its device’s performance. The current monitoring systems applied in large structures set up with numerous sensors, and the most varied types, which form compose network communication, in some cases wireless, even in to automated systems of data acquisition (DAQ) and processing of the results, which allow real-time and remote monitoring. However, many of the technologies used in these systems are relatively expensive and require specific operating knowledge, which in some cases makes their use impracticable. In this context, a DAQ system was developed with hardware from the Arduino platform, associated to mobile software for smartphone, which via Bluetooth, send and receive information from Arduino, to acquire strain, displacement and force data from the monitored structure, with real-time data transmission via the internet. Bending tests were conducted in metallic cantilever and reinforced concrete beams using strain gages, displacement transducers and load cell, with data acquired by commercial reference equipment and the system of this research. Comparing themselves with which satisfactory results were obtained.
