The borehole of this study is located in Gij\u00f3n (Asturias, Spain). The measurements were made through two fixed sets of sensors coupled to the geothermal pipe, constituting two independent installations: (a) a commercial device called \u201cHobo\u201d, which uses TMCx-HD-specific sensors based on resistors with variable resistance; and (b) a device built by this research group, which uses DS12B20 Maxim sensors, a bus 1-wire, and a recording device based on a conventional Arduino board. Temperature was registered every 5 min across several years. These measurements were used to thermally characterize the subsoil, determining the apparent thermal diffusivity, and to study the thermo-hydrogeology of the Lower Jurassic Gij\u00f3n\u2019s formation made of Liassic limestones and dolomites. This work is part of the Q-Thermie group\u2019s research called \u201cShallow Thermal Energy\u201d.<\/jats:p>","DOI":"10.3390\/s22134945","type":"journal-article","created":{"date-parts":[[2022,7,1]],"date-time":"2022-07-01T01:40:36Z","timestamp":1656639636000},"page":"4945","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["A Device to Register Temperature in Boreholes in Northwest Spain for Geothermal Research"],"prefix":"10.3390","volume":"22","author":[{"given":"Germ\u00e1n","family":"Marcos-Robredo","sequence":"first","affiliation":[{"name":"Departamento de Energ\u00eda, Universidad de Oviedo, 33003 Oviedo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2229-4586","authenticated-orcid":false,"given":"Miguel \u00c1ngel","family":"Rey-Ronco","sequence":"additional","affiliation":[{"name":"Departamento de Energ\u00eda, Universidad de Oviedo, 33003 Oviedo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7278-3847","authenticated-orcid":false,"given":"Mar\u00eda Pilar","family":"Castro-Garc\u00eda","sequence":"additional","affiliation":[{"name":"Departamento de Energ\u00eda, Universidad de Oviedo, 33003 Oviedo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4702-1314","authenticated-orcid":false,"given":"Teresa","family":"Alonso-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Departamento de Explotaci\u00f3n y Prospecci\u00f3n de Minas; C\u00e1tedra Hunosa, Universidad de Oviedo, 33003 Ovied, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,30]]},"reference":[{"key":"ref_1","first-page":"313","article-title":"Temperature Measurements in Boreholes\u2014An Overview of Engineering and Scientific Applications","volume":"33","author":"Prensky","year":"1992","journal-title":"Log Anal."},{"key":"ref_2","unstructured":"Hill, A.D.
