“…It includes three main components: An instrumentation amplifier, INA155; an anti-aliasing filter, MAX7404, which is an 8th-order, low-pass, elliptic, switched-capacitor filter; and a programmable gain amplifier, LTB5 86910-1. The capacity of this design for the conditioning of seismic signals has been demonstrated in reference [23]. In order to physically implement the circuit, a PCB has been designed (Figure 4).…”

“…In this way, in case of an unexpected stop of the data acquisition, all of the data are saved, until the moment of the unexpected stop. This is an important improvement in relation to other previous implementations [23,29], where the data file was opened and closed just once, at the beginning and the end of the data acquisition, respectively.Reading and decoding the NMEA data and saving the GPS information in a data file. In order to obtain a more reliable estimation of the position, GPS information is taken every three seconds and appended to the ASCII file, created in step 2 ({Message ID = 01}).…”

The characterization of soil is essential for the evaluation of seismic hazard, because soil properties strongly influence the damage caused by earthquakes. Methods based on seismic noise are the most commonly used in soil characterization. Concretely, methods based on seismic noise array measurements allow for the estimation of Rayleigh wave dispersion curves and, subsequently, shear-wave velocity profiles. The equipment required for the application of this technique is usually very expensive, which could be a significant economic challenge for small research groups. In this work, we have developed a wireless multichannel seismic noise recorder system (Geophonino-W), which is suitable for array measurements. Each station includes a microcontroller board (Arduino), a conditioning circuit, an Xbee module, an SD card, and a GPS module. Several laboratory tests were carried out in order to study the performance of the Geophonino-W: A frequency response test (impulse response and noise); synchronization test; and battery duration test. Comparisons of Geophonino-W with the commercial systems and field measurements were also carried out. The estimated dispersion curves obtained using the proposed system were compared with the ones obtained using other commercial equipment, demonstrating the effectiveness of Geophonino-W for seismic noise array measurements. Geophonino-W is an economic open-source and hardware system that is available to any small research group or university.

“…This fact, together with the growing development of microcontrollers and open-source electronic platforms, has led to the development of seismic recorders by some researchers. In this way, we can find in the literature different works based on one [24,25], three [26], and more than three [27][28][29][30][31][32] channel recorders.…”

“…In order to make the developed designs accessible to the greatest number of researchers, the authors have in recent years been developing different open-hardware and open-software models for one and three components [25,26]. Following this research line, in this work we have developed a new multi-channel data acquisition system with the following characteristics: open-hardware, open-software, easy to implement, and low-cost.…”

The analysis of seismic noise provides a reliable estimation of the soil properties, which supposes the starting point for the assessment of the seismic hazard. The horizontal-to-vertical spectral ratio technique calculates the resonant frequency of the soil just by using a single three-component sensor. Array measurements require at least several vertical sensors registering simultaneously and their analysis provides an estimation of the surface waves dispersion curve. Although these methods are relatively cheaper than other geotechnical techniques, the cost of the sensors and the multi-channel data acquisition system means that small research groups cannot afford this kind of equipment. In this work, two prototypes for registering seismic noise have been developed and implemented: a three-channel acquisition system, optimized for working with three-component sensors; and a twelve-channel acquisition system, prepared for working simultaneously with twelve vertical geophones. Both prototypes are characterized by being open-hardware, open-software, easy to implement, and low-cost. The main aim is to provide a data acquisition system that can be reproduced and applied by any research group. Both developed prototypes have been tested and compared with other commercial equipment, showing their suitability to register seismic noise and to estimate the soil characteristics.

“…Notably, more software tools are becoming available to directly interface with hardware for managing disparate sensor data over networks [ 5 , 6 ], automate the operation of laboratory instruments [ 7 ], and directly manage laboratory experiments [ 8 ]. Platforms such as Arduino and Raspberry Pi, with highly versatile open-source hardware, friendly development environments, and large communities of users have resulted in massive numbers of highly-customized sensor systems to address needs in precision agriculture [ 9 , 10 ], plant phenotyping [ 11 ], particle physics [ 12 ], geosciences [ 13 , 14 ], long-term low-power environmental monitoring [ 15 ], micro-scale process control [ 16 ], and other analytical [ 17 , 18 , 19 ] and educational [ 12 , 20 , 21 , 22 ] applications.…”

Advances in scientific knowledge are increasingly supported by a growing community of developers freely sharing new hardware and software tools. In this spirit we have developed a free Android app, ABE-VIEW, that provides a flexible graphical user interface (GUI) populated entirely from a remote instrument by ascii-coded instructions communicated wirelessly over Bluetooth. Options include an interactive chart for plotting data in real time, up to 16 data fields, and virtual controls including buttons, numerical controls with user-defined range and resolution, and radio buttons which the user can use to send coded instructions back to the instrument. Data can be recorded into comma delimited files interactively at the user’s discretion. Our original objective of the project was to make data acquisition and control for undergraduate engineering labs more modular and affordable, but we have also found that the tool is highly useful for rapidly testing novel sensor systems for iterative improvement. Here we document the operation of the app and syntax for communicating with it. We also illustrate its application in undergraduate engineering labs on dynamic systems modeling, as well as for identifying the source of harmonic distortion affecting electrochemical impedance measurements at certain frequencies in a novel wireless potentiostat.
