An Internet of Things (IoT) strain-sensing system with LoRa telemetry and asset metadata was evaluated on a cantilever fixture. The node converted tare-referenced bridge counts to apparent strain, applied temperature compensation using a lagged temperature term, evaluated alarms locally, and buffered summaries for LoRa transfer. Histories were assessed using sequence continuity and a 32-bit cyclic redundancy check (CRC-32). Ten monotonic loading runs showed linear responses to nominal screw advance (R2 &gt; 0.9997); fitted slopes had a coefficient of variation of 0.55%. Across three fixed-setting tests spanning 5.1\u20138.0 \u00b0C, unchanged embedded compensation reduced the magnitude of fitted apparent thermal sensitivity by 89.1\u201395.5%. In all 45 operator-controlled alarm trials, trigger or non-trigger outcomes matched expectations recorded before dashboard inspection. Of 60 planned application-layer history transfers, 50 passed; the remaining ten comprised four failures, three interruptions, and three invalid or contaminated trials. Passed transfers included exact reconstruction of a 1024-record circular buffer. Retrieved metadata passed CRC-32 verification and matched the registered laboratory asset. These results characterize a one-asset laboratory workflow before packaged-bolt, underground, and multi-asset validation.<\/jats:p>","DOI":"10.3390\/s26185686","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T08:10:22Z","timestamp":1788855022000},"page":"5686","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of an IoT Strain-Sensing System with LoRa Telemetry and Asset Metadata"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-7959-7097","authenticated-orcid":false,"given":"Xiaoxiao","family":"Bu","sequence":"first","affiliation":[{"name":"School of Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-1662-0106","authenticated-orcid":false,"given":"Shenshi","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Mathematics and Physics, University of Wollongong, Wollongong, NSW 2522, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-6612-1291","authenticated-orcid":false,"given":"Henry","family":"Gong","sequence":"additional","affiliation":[{"name":"Roobuck Pty Ltd., Brookvale, NSW 2100, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1843-3767","authenticated-orcid":false,"given":"Tommy","family":"Chaung","sequence":"additional","affiliation":[{"name":"Roobuck Pty Ltd., Brookvale, NSW 2100, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7655-514X","authenticated-orcid":false,"given":"Enbang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mathematics and Physics, University of Wollongong, Wollongong, NSW 2522, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8676-7461","authenticated-orcid":false,"given":"Zhengyi","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1013","DOI":"10.1016\/S1365-1609(99)00064-7","article-title":"Analytical Models for Rock Bolts","volume":"36","author":"Li","year":"1999","journal-title":"Int.
