Evaluación de la transmisión de datos con tecnología IOT de un prototipo de sistema de seguridad en cocinas a gas para la prevención de incendios domésticos.

Abstract

A safety prototype for traditional gas stoves was implemented with real-time remote monitoring of the state of a kitchen and its surroundings, with the aim of contributing to fire prevention measures through strategically located sensors and actuators. A comparative analysis determined that the communication technology that best suits the prototype is Wi-Fi, the data speeds in its different versions propose a bridge for the massive traffic of information, its coverage, channeling and provision of services, led to the fact that the system may over time include improvements to strengthen prevention and therefore generate scalability. The devices used were chosen based on the data of the most useful elements in the market; of the weights of each device, of the percentages that the Likert method yielded and in accordance with the categories established in said scale, it was established that the devices with the highest performance are: Node MCU ESP-32S, MQ-2, DS18B20, reaching an efficacy of 78.46%, 78.46% and 88.57% respectively. MG996R was incorporated as actuators and SIM800L together with a buzzer as notification and alert stage. The Arduino IoT Cloud platform provided tools, turning the prototype into a set of instruments with the ability to configure, program, and monitor in real time oriented to the purpose of this research. Under controlled conditions and a set of samples, it was possible to reach an error level of ± 0.1375 °C in the sensor that was taken as reference, reaching a highly acceptable precision threshold. Based on the established needs, the system brought together a set of measures aimed at prevention, contemplating a relatively low cost for its implementation and operation, incorporating a manual and automatic way of working, effective and continuous devices, and an interactive interface.
