Item Sistema en línea para el monitoreo de humedad y temperatura en el laboratorio de metrología de una clínica de la ciudad de cali(Universidad Santiago de Cali, 2025) Rojas Perdomo, Stefany; Marroquin Torres, Angie Sthefany; Mamian Homen, Vladimir; Arcos Hurtado, Edgar Francisco (Director)Isothermal enclosures are medical and industrial equipment designed to condition a closed space to maintain appropriate temperature and humidity levels. These enclosures may sometimes fail due to manufacturing defects, lack of maintenance, material wear, battery support issues, or human error. If not detected in time, such failures can compromise environmental conditions, especially within the climate chamber, and negatively impact processes such as the calibration of thermo-hygrometers. To address this issue, this work presents the development of an online measurement system that enables real-time monitoring of temperature and humidity conditions in a specific laboratory. This technological solution integrates a system based on an ESP32 microcontroller and humidity and temperature sensors, with data stored in the cloud using InfluxDB and visualized through the Grafana platform. Four monitoring devices were developed and deployed in the equipment room, the mass area, the pressure area, and the temperature and humidity area (including the climate chamber). Over a one-month evaluation period, more than 43,200 records per sensor were collected (one sample per minute), which allowed for the identification of out-of-range behaviors during at least four simulated failure events. The system demonstrated a reduction in the average failure detection time of over 85% compared to manual verification, thus improving response capacity to critical variations. Additionally, energy autonomy tests were conducted by simulating a power outage, during which the devices continued to operate normally using a rechargeable battery for a period of three hours. The results indicate that the system not only significantly reduces response time to failures but also optimizes calibration processes, enables traceability of environmental conditions, and ensures continuous monitoring in compliance with ISO/IEC 17025:2017.
