Implementación de un prototipo para el control, monitoreo y detección de fugas de gas doméstico mediante tecnología IoT.

Abstract

The main objective of this curricular integration research project was to implement a prototype based on IoT to control, monitor, and detect gas leaks in domestic environments. The Anti-Leak system comprises three key nodes: The Gas and Weight Node, responsible for collecting and sending weight and gas leak data to a database using WiFi. Two Gas and Smoke Leak Detection Nodes, responsible for collecting and transmitting information about gas and smoke leaks to the same database via WiFi. In addition, the system includes a Central Display and Information Node, which displays the data stored in the database. An Android device application allows viewing node parameters, controlling the Solenoid Valve, receiving alerts and notifications, and even sending GSM messages to the provider to manage situations effectively and safely. Validation tests were conducted to evaluate the accuracy of the weight, gas, and smoke sensors, obtaining results with absolute errors of 0.005% and 0%, respectively, which remained within the expected ranges for each sensor. Regarding communication tests, an optimal connection between the nodes was confirmed, and it was verified that alert notifications were correctly sent to both the Central Node and the mobile application, including the successful transmission of GSM messages from the application. In terms of autonomy, it was determined that the battery could power the Gas and Weight Node for 158 hours, the Central Node for 8 hours, and the Gas and Smoke Leak Detection Node for a maximum of 6 hours. These results confirm that the implemented Anti-Leak system meets the previously established requirements.
