“…In [22] the Arduino microcontroller was used along with low-cost sensors for vibration instrumentation. As in [11], the Arduino microcontroller is used for the instrumentation of vibrations in systems with various degrees of freedom by means of MEMS accelerometers. In [23] the Arduino was used with the wireless MEMS sensors in order to monitor the Himera viaduct in Italy.…”

This paper presents a methodology for the measurement of strain by means of strain-gauges, where the data acquisition is done by using an Arduino Uno board, due to the low-cost and the easy manipulation of this microcontrollers. The measured signal conditioning is performed by means of a Wheatstone Bridge and then discretized by an Analog-Digital Converter (ADC) external to the Arduino. For the validation of the proposed measurement system, experiments are performed on a cantilever beam and on a cantilever-supported shaft, where the experimental results are compared with those obtained analytically and by simulation using the finite element method. The results obtained are in agreement with the literature and demonstrate that the proposed system has satisfactory accuracy.

In this study, the influence of the clamped-free beam specimen length on the measured fundamental vibration frequencies of flat sandwich beams is investigated. First, sandwich beams having flat galvanized steel faces, and a rigid foam core are produced, and clamped beam vibration tests are conducted on specimens having three different lengths. The experimental results obtained are compared with the numerical results obtained using a 1D finite element model. The results obtained show that the clamped beam vibration test yields satisfactory results, and the longer specimens yield more accurate results. Figure A. The experimental setupPurpose: The main purpose is to determine the influence of specimen length on the vibration test results.Theory and Methods: The experimental results obtained using a MEMS type accelerometer are compared with the numerical results obtained using a shear deformable beam finite element model. Results:The results obtained show that the numerical and experimental results are in good agreement, especially for longer specimens. Conclusion: (i)The numerical and experimental results obained are in better agreement for longer beam specimens. (ii) It is observed that the frequency ratio decreases with increasing specimen length. (iii) The material properties used in the numerical model are verified by the experimental results obtained in this study. (iv) It is shown that MEMS type accelerometers can be used to conduct simple vibration tests. (v) The results obtained show that the the not-perfect clamped end conditions cause deviations between the numerical and the experimentally obtained results.

“…With the widespread of open-source electronics platforms based on easy-to-use hardware and software, such as Arduino (Arduino, 2018a), the development of low-cost vibration-monitoring systems have been progressively explored. Several works have been conducted with the Arduino platform and commercial low-cost accelerometers, aiming the development of SHM and control systems with diverse capabilities and finalities (Andò, Baglio and Pistorio, 2014;Chacón, Oller, 2016;Peralta et al, 2014;Iacono et al, 2017;Sohn, Rim and Lee, 2015;D'Emilia et al, 2017;Duc, Anh and Dinh, 2017;Patel and Patel, 2017;Varanis, Silva and Mereles, 2018). The commercial MEMS accelerometers used in these researches are: the tri-axial accelerometer ADXL 335, 345 and 350, from Analog Devices; the MPU 6050, from InvenSense, which is an Inertial Measurement Unit (IMU) comprising a tri-axial accelerometer and tri-axial gyroscope; and the triaxial accelerometer MMA 7455L and MMA 7361L, from NXP Semiconductors.…”

Sensing techniques based on accelerometers for modal parameters identification are among the most studied and applied in Structural Health Monitoring of civil structures. The advent of low-cost MEMS accelerometers and open-source electronic platforms, such as Arduino, have facilitated the design of low-cost systems suitable for modal identification, although there is still a lack of studies regarding practical application and comparison of commercially available low-cost accelerometers under SHM conditions. This work presents an experimental performance evaluation of six low-cost MEMS accelerometers for the identification of natural frequencies and damping ratios of a three-storey frame model and a reinforced concrete slab, as well as their noise characteristics. A low-cost Arduino-based data acquisition system was used. The results showed an overall good performance of the MEMS accelerometers, with identified natural frequencies errors within 1.02% and 7.76% of reference values, for the three-storey frame and concrete slab, respectively, and a noise density as low as 108 g/√Hz.
