Development of a Cloud-Connected Industrial Temperature and Humidity Monitoring System

Abstract: The present study focuses on the design and implementation of an Internet of Things (IoT)-based Industrial Temperature and Humidity Monitoring System utilizing the ESP32 microcontroller and the Blynk cloud platform. The proposed system enables real-time acquisition, processing, and visualization of environmental parameters such as temperature and humidity in industrial environments. Accurate control of these parameters is essential for maintaining product quality, ensuring equipment longevity, and providing a safe workplace. The DHT11 sensor is employed to measure temperature and humidity, while the ESP32 microcontroller, equipped with integrated Wi-Fi, processes the acquired data and transmits it to the Blynk cloud. Through the Blynk mobile application, users can remotely monitor live readings, analyze parameter fluctuations, and receive instant alerts when thresholds are exceeded. The system effectively eliminates the limitations of manual monitoring by providing continuous and automated supervision. Collected data can further support predictive maintenance and performance optimization. Due to its low cost, scalability, and reliability, the proposed system is well-suited for diverse industrial applications, including manufacturing, warehousing, and pharmaceuticals. This research demonstrates an efficient, intelligent, and user-oriented approach for enhancing industrial automation and operational safety through IoT integration..
