Our system offers certain advantages when compared to other similar solutions, allowing remote symptom and health monitoring that can be applied to isolated or quarantined people, without any external interaction with the patient. The IoT wearable device can monitor parameters of health condition like pulse, blood oxygen saturation, and body temperature, as well as the current location. To test the performance of the proposed system, two persons under quarantine were monitored, for a complete 14-day standard quarantine time interval. Based on the data transmitted to the monitoring center, the medical staff decided, after several days of monitoring, when the measured values were outside of the normal parameters, to do an RT-PCR test for one of the two persons, confirming the SARS-CoV2 virus infection. We have to emphasize the high degree of scalability of the proposed solution that can oversee a large number of patients at the same time, thanks to the LoRaWAN communication protocol used. This solution can be successfully implemented by local authorities to increase monitoring capabilities, also saving lives.<\/jats:p>","DOI":"10.3390\/s22020503","type":"journal-article","created":{"date-parts":[[2022,1,10]],"date-time":"2022-01-10T22:03:13Z","timestamp":1641852193000},"page":"503","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Internet of Things Concept in the Context of the COVID-19 Pandemic: A Multi-Sensor Application Design"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7734-4854","authenticated-orcid":false,"given":"Alexandru","family":"Lavric","sequence":"first","affiliation":[{"name":"Computers, Electronics and Automation Department, Stefan Cel Mare University of Suceava, 720229 Suceava, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6188-5610","authenticated-orcid":false,"given":"Adrian I.","family":"Petrariu","sequence":"additional","affiliation":[{"name":"Computers, Electronics and Automation Department, Stefan Cel Mare University of Suceava, 720229 Suceava, Romania"},{"name":"MANSiD Research Center, Stefan Cel Mare University of Suceava, 720229 Suceava, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8005-2115","authenticated-orcid":false,"given":"Partemie-Marian","family":"Mutescu","sequence":"additional","affiliation":[{"name":"Computers, Electronics and Automation Department, Stefan Cel Mare University of Suceava, 720229 Suceava, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9667-6245","authenticated-orcid":false,"given":"Eugen","family":"Coca","sequence":"additional","affiliation":[{"name":"Computers, Electronics and Automation Department, Stefan Cel Mare University of Suceava, 720229 Suceava, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentin","family":"Popa","sequence":"additional","affiliation":[{"name":"Computers, Electronics and Automation Department, Stefan Cel Mare University of Suceava, 720229 Suceava, Romania"},{"name":"MANSiD Research Center, Stefan Cel Mare University of Suceava, 720229 Suceava, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"877","DOI":"10.1080\/14787210.2021.1863146","article-title":"An Update on COVID-19 Pandemic: The Epidemiology, Pathogenesis, Prevention and Treatment Strategies","volume":"19","author":"Tsang","year":"2021","journal-title":"Expert Rev.
