In the context of rising urbanization, the surge in air conditioner usage has become a significant contributor to energy consumption. To address this, our research introduces an innovative Air Conditioner Monitoring System (ACMS) designed to optimize energy usage, enhance system efficiency, and ensure optimal indoor conditions. The proposed system employs cutting-edge sensors to monitor crucial parameters, including current, voltage, power consumption, and room temperature in real-time. By integrating these metrics into a unified framework, the ACMS facilitates proactive management and enables users to make informed decisions for energy conservation. The collected data is processed through advanced algorithms to predict potential faults or inefficiencies, allowing for preemptive maintenance and reducing downtime. Furthermore, the system supports remote monitoring and control, providing users with the flexibility to manage air conditioning settings from any location. Practical implementation and performance evaluations demonstrate the system's effectiveness in improving energy efficiency, reducing operational costs, and enhancing overall sustainability. This research contributes to the development of intelligent solutions for air conditioning systems, addressing the growing need for energy conservation in the face of expanding urbanization. The modularity of the proposed system allows for seamless customization and integration of additional features, paving the way for future advancements in intelligent climate control systems.
