Intelligent IoT Systems: From Research to Real-World Solutions

In present days, energy consumption is becoming a major concern for individuals, businesses, and agriculture. Inefficient energy consumption contributes to environmental degradation by raising electricity bills and increasing reliance on non-renewable resources. This approach gives a design and implements an IoT-based Smart Energy Management System for real-time monitoring, predictive automation, and cloud-based control of electrical appliances in smart homes. The system was created using various sensors to track voltage, current, temperature, occupancy and light. Real-time automation was obtained using relay modules and a servo motor for curtain automation. Firebase Realtime Database was utilised for cloud storage, control, and predictive data retrieval. Energy consumption was calculated in kilowatt-hours based on voltage and current values. Manual, schedule-based, and predictive override were implemented. The system effectively monitored energy consumption and reduced power levels by 18%. It automatically shut down equipment when idle or in accordance with pre-scheduled occupancy estimates. The system responded in real-time to sensor inputs and user-scheduled events. Power telemetry and daily logging were always synchronised with Firebase to enable smooth cloud updates and user interaction. The proposed system offers a safe, scalable, and intelligent home energy management system for the future through the use of IoT sensors and cloud technology to enable automation, predictive control, safety, and future-proof compatibility with new smart grid infrastructure for improved sustainability and operational efficiency.
