The commercial data acquisition instruments designed for three-component microtremor measurements are usually very expensive devices. In this paper, a low-cost, computer-aided and geophone-based system designed to record, monitor and analyze the three-component microtremor data, is presented. This proposed system is not a simple data acquisition system. It is also an integrated system developed to interpret the microtermor data without any external software. Therefore, the predominant frequency and ground amplification factor of survey area can be easily estimated by using this system. The proposed system has several features such as 200\u2009Hz sampling frequency, approximately 72\u2009dB dynamic range, text data format and data analysis tools. This system consists of a graphical user interface developed by using .NET Framework 4.5.2 and an external hardware that includes signal conditioning circuits, voltage converter circuit, external analog-to-digital converter and Arduino Uno board. The proposed system uses the low-cost and high gain geophones with 4.5\u2009Hz natural frequency to measure three-component microtremor data. The developed software undertakes many tasks such as communication between the external hardware and computer, transferring, monitoring and recording the seismic data to computer, and interpretation of the recorded data using the Nakamura method. To demonstrate the accuracy and precision of the proposed system, the channel consistency and internal noise measurement tests are performed. Besides, the proposed system is compared to a commercial digitizer and the obtained results are presented in this study.<\/jats:p>","DOI":"10.5194\/gi-2020-11","type":"posted-content","created":{"date-parts":[[2020,5,26]],"date-time":"2020-05-26T04:41:34Z","timestamp":1590468094000},"source":"Crossref","is-referenced-by-count":2,"title":["A geophone-based and low-cost data acquisition and analysis system designed to microtremor measurements"],"prefix":"10.5194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6171-7684","authenticated-orcid":false,"given":"Ozkan","family":"Kafadar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3145","container-title":[],"original-title":[],"deposited":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T16:28:21Z","timestamp":1738340901000},"score":1,"resource":{"primary":{"URL":"https:\/\/gi.copernicus.org\/articles\/9\/365\/2020\/gi-9-365-2020-discussion.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,5,26]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5194\/gi-2020-11","relation":{"has-comment":[{"id-type":"doi","id":"10.5194\/gi-2020-11-AC1","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-AC5","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-AC2","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-AC4","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-AC3","asserted-by":"object"}],"has-review":[{"id-type":"doi","id":"10.5194\/gi-2020-11-RC1","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-RC3","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-EC1","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-RC2","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-RC4","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-2020-11-EC2","asserted-by":"subject"}],"is-preprint-of":[{"id-type":"doi","id":"10.5194\/gi-9-365-2020","asserted-by":"subject"},{"id-type":"doi","id":"10.5194\/gi-9-365-2020","asserted-by":"object"}]},"subject":[],"published":{"date-parts":[[2020,5,26]]},"subtype":"preprint"}}
