Automatic Fan Regulation Based on Temperature Using Audrino

Abstract This project focuses on developing an automatic fan regulation system based on temperature using Arduino. The system is designed to provide an energy-efficient and cost-effective solution for maintaining optimal environmental conditions. It automatically adjusts the speed of the fan according to the surrounding temperature, ensuring comfort and reducing power consumption. The core component of this system is an Arduino microcontroller, which processes temperature data obtained from a temperature sensor, such as the DHT11 or LM35. The fan’s speed is controlled using a Pulse Width Modulation (PWM) technique, which is implemented through a motor driver or MOSFET circuit. The system continuously monitors the temperature, and based on predefined thresholds, the Arduino dynamically adjusts the fan speed in real time. This project has applications in residential, industrial, and agricultural settings where temperature regulation is essential. By automating the process, it eliminates the need for manual fan speed adjustments and promotes energy conservation. The system is highly scalable and can be enhanced by integrating additional features like LCD displays, IoT connectivity, or remote control for better usability and monitoring.
