“…The output voltage is expressed in terms of a single differential voltage, which is then converted into a force value as follows: (10) where R.C (rated capacity) is the maximum load that the load cell can bear and still operate under (>0.8 load) (tf), and R (rated output) is the output voltage that the load cell produces at the rated capacity per excitation volt at the input terminals minus the output voltage at the minimum load (mV/V). This study uses a low-profile, four-wire tension or compression load cell, model UL-T5, manufactured by Dacell [28], and the specifications of this load cell are shown in Table 1.…”

“…The application of Arduino ® in geotechnical engineering is exemplified through the development of hardware and software solutions for estimating and regulating soil moisture, as demonstrated in the study of Garg et al [9]. Zaman et al [10] utilized geophone sensors and an Arduino ® microcontroller as the data acquisition center, which exemplifies an application of Arduino ® as a cost-effective approach to identify soil types and layers for preliminary geotechnical characterization. Sensors based on Electro-Mechanical and Micro-Electro-Mechanical-System (MEMS) technologies, along with external hardware components such as analog-to-digital converters and Arduino ® Uno boards, have the potential for use in various seismic and force signal monitoring devices [11].…”

This research presents an innovative solution aimed at addressing the cost and accessibility challenges associated with soil stiffness analysis in construction projects. Traditional lightweight deflectometer (LWD) systems have limitations due to their high cost and proprietary nature, prompting the need for a more widely accessible technology. To fulfill this purpose, a low-cost, open-source LWD onboard sensor signal interpretation system, utilizing Electro-Mechanical and Micro-Electro-Mechanical-System (MEMS) technology-based sensors in conjunction with an Arduino® Uno and ADS1262 Breakout Board, has been developed. This system efficiently processes raw signal data into deflection and force units, enabling precise soil property analysis. Thorough enhancements, calibration, and alignment procedures have been applied and validated through field tests, which have produced highly satisfactory results. By significantly reducing costs while maintaining accuracy, this developed system has the potential to popularize quality control and assurance practices in the construction industry. This open-source approach not only enhances affordability but also broadens accessibility, making soil property analysis more efficient and attainable for a wider range of construction projects.

The MASW (Multi-Channel Analysis of Surface Waves) was conducted on fill soil at Tembagapura Freeport Mining. The fill was very dense and is the landfills where people dumped waste disposal like car tire rubber etc. Several attempts were made to make boreholes to collect soil samples and to run SPT (Standard Penetration Test), but they failed. The fill was so dense that the employed drill bits were worn out when penetrating the soil. The MASW team was invited to carry out the measurements and to produce shear wave velocities of the layers, which correspond to SPT Number. The number of measured MASW points was 8 points. They were successfully carried out on the surface of the fill without borings. The offset distance between the hammer blows, and the first geophone was 18 m, and the interval distance between 4.5 Hz geophones was 3 m. The MASW measurements resulted in an average shear velocity of 400 m/s which confirmed the soil was very dense soil. The information regarding the shear wave velocities of the layers was adopted as input of earthquake engineering software to predict the amplification when the earthquake happens.
