In this article, we present a low-cost system based on the Raspberry Pi platform to measure the overall equipment effectiveness (OEE) in real time, and we propose two filtering mechanisms for electromagnetic interferences (EMIs) to measure OEE accurately. The first EMI filtering mechanism is the database filter (DBF), which has been designed to record sealing signals accurately. The DBF works on the database by filtering erroneous signals that have been inserted in it. The second mechanism is the smart coded filter (SCF), which is used to filter erroneous signals associated with machine availability measurements. We have validated our proposal in several production lines in a food industry. The results show that our system works properly, and that it considerably reduces implementation costs compared with proprietary systems offering similar functions. After implementing the proposed system in actual industrial settings, the results show a mean error (ME) of -0.43% and a root mean square error (RMSE) of 4.85 in the sealing signals, and an error of 0% in the availability signal, thus enabling an accurate estimate of OEE. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.476 2021 COMPUTER SCIENCE, INFORMATION SYSTEMS 79 / 164 = 0.482 2021 Q2 T2 TELECOMMUNICATIONS 43 / 93 = 0.462 2021 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 105 / 277 = 0.379 2021 Q2 T2 0.927 2021 Computer Science (miscellaneous) 2021 Q1 Engineering (miscellaneous) 2021 Q1 6.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sanguesa, JA Universidad de Zaragoza (orcid)0000-0001-7657-0075 Martinez, FJ Universidad de Zaragoza (orcid)0000-0001-6945-7330 Garrido, P Universidad de Zaragoza (orcid)0000-0002-1750-7225 Calafate, CT 5007 035 Universidad de Zaragoza Dpto.
