Abstract

This research focuses on developing a cost-effective IoT-based system for energy and environmental monitoring in manufacturing industries. The proposed system collects real-time data on temperature, humidity, and energy consumption from various devices using different communication protocols such as Modbus, TCP/IP, and MQTT. The key components of the system include: Industrial energy meter (EasyLogic PM2100) integrated with a Modbus gateway to retrieve energy data. ESP32-based energy meter using current and voltage sensors to monitor energy consumption of electrical equipment. ESP32-based environment monitoring device with temperature and humidity sensors. Raspberry Pi-based MQTT broker that acts as an edge device to process sensor data and transmit it to the cloud. A web client that subscribes to the MQTT broker, stores the data in a MySQL database, and provides a user-friendly interface for visualization and analysis. The system architecture utilizes the MQTT publish-subscribe protocol for efficient and reliable data transmission, even in low-bandwidth or unreliable network conditions. The collected data is stored in a cloud-based database and can be accessed through a web-based dashboard, allowing users to monitor trends, analyze fluctuations, and make informed decisions regarding energy usage and environmental conditions within the manufacturing facility. The system has been thoroughly tested and validated, demonstrating high accuracy and reliability in data collection. Its scalability and adaptability ensure compatibility with existing infrastructure, making it a versatile solution for manufacturing industries seeking to enhance their energy and environmental management practices.
