The sensors were positioned inside a climate chamber and connected outside to a micro-controller via a network cable. The chamber temperature was increased systematically over a wide range from \u221220      \u00b0C to 55      \u00b0C. A set of calibration curves was produced from the best fitting second-order polynomial curves for the offset in temperature between the sensor and reference. An improvement in accuracy of \u00b10.15      \u00b0C is with respect to the mentioned temperature range, compared to the significantly higher value reported of \u00b10.5      \u00b0C by the manufacturer for similar conditions. In summary, we demonstrate a significant improvement in the calibration of a low-cost, smart sensor frequently used in research and academic projects over a useful range of temperatures.<\/jats:p>","DOI":"10.3390\/s18124087","type":"journal-article","created":{"date-parts":[[2018,11,22]],"date-time":"2018-11-22T09:18:25Z","timestamp":1542878305000},"page":"4087","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Enhanced Accuracy of CMOS Smart Temperature Sensors by Nonlinear Curvature Correction"],"prefix":"10.3390","volume":"18","author":[{"given":"Gareth D.","family":"Lewis","sequence":"first","affiliation":[{"name":"Signal and Image Centre, Royal Military Academy, Avenue de la Renaissance 30, B-1000 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Merken","sequence":"additional","affiliation":[{"name":"Signal and Image Centre, Royal Military Academy, Avenue de la Renaissance 30, B-1000 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marijke","family":"Vandewal","sequence":"additional","affiliation":[{"name":"Signal and Image Centre, Royal Military Academy, Avenue de la Renaissance 30, B-1000 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,22]]},"reference":[{"key":"ref_1","unstructured":"Incropera, F., and DeWitt, D.
