• Abstract:

  Chemical engineering students at the National Technological Institute of Mexico, Aguascalientes Technological Institute Campus, particularly those who do internships in the Industrial Analysis laboratory, face an opportunity to incorporate Information and Communication Technologies (ICT) to strengthen safety in experimental environments. In response to this need, SAFELAB was developed, a Comprehensive Real-Time Monitoring System based on a scalable software architecture, whose objective is to significantly improve safety conditions through the early detection of toxic gases and the implementation of preventive and corrective measures.
  The project was organized in three stages: (1) analysis of the gases used in the laboratory to determine their hazardousness and select the appropriate sensors; (2) design and implementation of an Internet of Things (IoT) prototype to monitor air quality in real time; and (3) development of a mobile application capable of issuing immediate alerts in case of dangerous concentrations.
  The results were satisfactory: the system demonstrated its ability to identify the presence of harmful gases and issue effective notifications to the user via their mobile device. The proposal represents a scalable, economical, and functional technological solution for educational laboratories that handle hazardous substances.
