Desenvolvimento e validação de um sistema IOT para monitoramento de câmaras-frias.

Abstract

Continuous monitoring of refrigerated environments is crucial for product preservation and energy efficiency. However, existing commercial solutions often present high costs and low flexibility. In this context, this work aimed to develop and validate a low-cost IoT solution for cold room monitoring. The system architecture was based on an ESP32-C3 microcontroller, responsible for collecting data from temperature, humidity, and door status sensors in an emulated environment. The data were processed and transmitted to a notification system via bot and to a data visualization platform through a dashboard. The results demonstrated the effectiveness of the prototype, which successfully monitored the variables and automatically sent alerts whenever the preconfigured temperature limits (above 10◦C) and humidity (above 80%) were exceeded, validating event detection in relevant scenarios. It is concluded that the proposed solution highlights the potential of modular and low-cost technologies for refrigerated product monitoring and contributes to sustainability.
