The use of Personal Protective Equipment (PPE) based on ICTs reduces the risk of accidents in the workplace, thanks to the capacity of the equipment to make decisions on the basis of environmental factors. Paradigms such as the Industrial Internet of Things (IIoT) and Artificial Intelligence (AI) make it possible to generate PPE models feasibly and create devices with more advanced characteristics such as monitoring, sensing the environment and risk detection between others. The working environment is monitored continuously by these models and they notify the employees and their supervisors of any anomalies and threats. This paper presents a smart helmet prototype that monitors the conditions in the workers\u2019 environment and performs a near real-time evaluation of risks. The data collected by sensors is sent to an AI-driven platform for analysis. The training dataset consisted of 11,755 samples and 12 different scenarios. As part of this research, a comparative study of the state-of-the-art models of supervised learning is carried out. Moreover, the use of a Deep Convolutional Neural Network (ConvNet\/CNN) is proposed for the detection of possible occupational risks. The data are processed to make them suitable for the CNN and the results are compared against a Static Neural Network (NN), Naive Bayes Classifier (NB) and Support Vector Machine (SVM), where the CNN had an accuracy of 92.05% in cross-validation.<\/jats:p>","DOI":"10.3390\/s20216241","type":"journal-article","created":{"date-parts":[[2020,11,1]],"date-time":"2020-11-01T20:05:25Z","timestamp":1604261125000},"page":"6241","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":117,"title":["Smart Helmet 5.0 for Industrial Internet of Things Using Artificial Intelligence"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6934-6833","authenticated-orcid":false,"given":"Israel","family":"Campero-Jurado","sequence":"first","affiliation":[{"name":"Laboratoire de l\u2019Informatique du Parall\u00e9lisme 46 all\u00e9e d\u2019Italie, 69007 Lyon, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0434-6538","authenticated-orcid":false,"given":"Sergio","family":"M\u00e1rquez-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"BISITE Research Group, University of Salamanca, Calle Espejo s\/n.
