Diseño de un sistema IoT para medición de variables ambientales de dispositivos TI alojados en racks de data centers mediante un módulo ESP32 y MQTT.

Abstract

The management of critical infrastructures, such as those used by Internet Service Providers (ISP), faces emerging challenges related to the monitoring of environmental conditions in their racks. These conditions, especially fluctuations in temperature and humidity, can compromise the operability of key devices such as routers and switches if not kept within acceptable ranges. This project addresses the need for an accurate and real-time system to oversee these variables. Our primary goal is to develop an IoT system, leveraging the potential of the ESP32 module and the DHT22 sensor, to capture, process, and transmit information about temperature and humidity in data center racks. Using the MQTT protocol, we ensure efficient and reliable data transmission to a cloud API, facilitating remote access and real-time decision-making. With in this study, we delve into the theoretical foundations of sensor networks and IoT, illustrating their relevance and applicability in industrial and business contexts. Through the programming and configuration of the ESP32 along with the DHT22 sensor, we demonstrate the effectiveness of our proposed solution, highlighting its accuracy and reliability in environmental monitoring. In conclusion, this work presents an innovative and cost-effective solution to address a key operational issue in data centers, proposing a robust IoT design that can be adapted and scaled according to the specific needs of different infrastructures.
