Abstract- This paper gives a new and creative IoT-based smart fan system for cooling with energy efficiency in various applications – residential, commercial as well as industrial surroundings. Traditional cooling systems usually depend on static control mechanisms. These cannot adjust to actual environmental conditions and result in extra energy consumption and reduced efficiency too. In order to tackle these challenges, our proposed system integrates an advanced temperature-controlled fan that makes use of a dynamic Pulse Width Modulation (PWM) algorithm that lets us adjust fan speed based on real-time temperature variations around the fan. The system consists of – an NTC thermistor for precise temperature measurement, an Arduino Uno microcontroller for data processing, and an IoT-enabled mobile interface that automates user interactions, and reducing manual adjustments. Strict testing results show that the system successfully achieves a temperature stability of ±0.2°C and reduces power consumption by 27.1% as compared to traditional methods. Also, the modular design supports both DC as well as AC fans, increasing scalability and adaptability. This work bridges the gap between academic research and practical applications and sets a new standard for smart, future focused, thermal management solutions.
