“…Tese eforts focus on developing electronic systems from scratch using low-cost components, which tends to involve intricate electronic aspects [9][10][11], or using standard lowcost components and accessible prototyping platforms [12,13], such as Arduino, leading to a simpler approach that allows non-specialists in electronics to develop their own systems. Some representative works of this last case include developments of Wi-Fi sensor networks based on Arduino and ESP modules [14,15]; XBee wireless sensor networks with measurement nodes controlled by Arduino boards [16][17][18]; and radio-frequency networks based on Arduino boards [19,20]. Low-cost SHM wireless systems may also be associated with IoT (Internet of Tings) applications to enable data streams across platforms and support datadriven processes [21,22].…”

Structural health monitoring (SHM) has gained importance because many structures are approaching the end of their design life and demanding maintenance and monitoring. Low-cost solutions may push forward a widespread implementation of SHM on infrastructures but further investigation is still required to assess the performance of technically accessible, simple, and scalable low-cost systems. This work presents the development and validation of a low-cost vibration-based SHM multinode wireless system, based on the Arduino platform, for identification of modal parameters in civil infrastructures. Full details about the hardware and source code of the system are disclosed in an open repository, allowing its reproduction even by non-specialists in electronics. The sampling frequency stability of the system is experimentally characterized, and interpolation postprocessing algorithms are proposed to solve inherent limitations. The system is validated, and its performance is investigated in impulse and ambient vibration tests performed in a real-scale slab and a high-grade system. The data obtained from the proposed system in impulse tests allowed estimation of natural frequencies within 2%, and MAC values around 0.3 to 0.9, in relation to those estimated with the high-grade system. However, the low-cost system was unable to produce usable data in ambient vibration tests.
