IoT-Driven Intelligent Automation for Energy Conservation in Lecture Halls

Abstract

The use of energy during the current age is imperative in efficiently utilizing resources and conserving energy from wastage. Efficiency in using energy not only saves costs but also helps towards sustainable environments. The current work presents an IoT-based Energy Saving System for Lecture Rooms with a purpose of automating and maximizing utilization of electrical appliances such as light, fan, and air conditioner. The system incorporates Passive Infrared (PIR) sensors to sense the presence of human beings and to turn on/off the lights and fans automatically. The room temperature is also sensed by a temperature sensor and is displayed on an LED display, and the AC operates on pre-set temperature ranges to make it fully energy efficient. The system is combined with a real-time monitoring system wherein users are able to observe energy usage through an IoT-based interface. The proposed system will reduce wastage of energy because of manual operation and prolonged usage of electrical appliances in unoccupied lecture rooms. With the application of fuzzy logic-based dynamic control, the system conserves a significant amount of energy, approximately 41.96%, in comparison with normal manual operation. Apart from that, the system provides real-time electrical load consumption data through a mobile app to enable better monitoring and management of electrical loads. The results indicate that the IoT-based energy-saving system effectively saves energy and promotes environmental sustainability through a decrease in greenhouse gas emissions. The research contributes to the development of smart and intelligent power-saving systems for schools and similar environments, increasing energy efficiency and cost-effectiveness.
