Industrial Environment Monitoring Using IoT: A Comprehensive Review on Temperature and Humidity Control

Abstract: This project introduces an IoT-based Industrial Temperature and Humidity Monitoring System built using an ESP32 microcontroller and the Blynk platform. The system is designed to continuously track and display environmental conditions such as temperature and humidity in industrial environments. Maintaining optimal temperature and humidity levels is essential for preserving product quality, safeguarding equipment, and ensuring worker safety. A DHT11 sensor is used to capture temperature and humidity data, which is then processed by the ESP32. Leveraging its built-in Wi-Fi, the ESP32 sends this data to the Blynk cloud platform, enabling users to view live readings, analyze trends, and receive instant notifications when the readings go beyond set thresholds—all through the Blynk mobile app. This automated setup removes the need for manual monitoring, providing a reliable and continuous supervision system. The stored data can further support predictive maintenance and system optimization. Due to its affordability, scalability, and efficiency, this solution can be implemented across industries such as manufacturing, warehousing, and pharmaceuticals. By integrating IoT, cloud connectivity, and mobile technology, the project offers a smart, real-time, and user-friendly approach to improving industrial automation and safety..
