The need for energy-efficient and eco-friendly cooling systems has led to the development of innovative smart air-cooling systems. The present study proposes a new Smart Solar Air Cooler with automation and energy-saving features for enhanced cooling performance with lower power consumption. Driven predominantly by solar power with a supportive power supply for uninterrupted operation, the cooler is suitable for application in urban and off-grid locations. The cooler features automatic temperature control, real-time water level monitoring, buzzer alert for low water level, and a dual-power operating system for high efficiency and reliability of operation. Through the use of advanced control methods, the system optimizes airflow and water distribution to provide substantially better cooling efficiency compared to conventional air coolers. Extensive experimentation and performance evaluation validate the system's prospects in delivering enhanced cooling, energy conservation, and greater operational sustainability. The study demonstrates the prospects of smart solar cooling technology in enabling eco-friendly and energy-efficient cooling systems, sustainable living, and harnessing renewable energy sources.
