Temperature Based Fan Speed Control Using Arduino

Abstract: In this project, we present an efficient temperature-based speed control system for a DC motor using an Arduino

microcontroller. The system is designed to automatically regulate the speed of the motor in response to temperature variations,

making it suitable for applications like cooling systems, industrial automation, and smart appliances. The system consists of a

temperature sensor (such as an LM35 or DHT11) that continuously monitors the ambient temperature and sends data to the

Arduino. Based on predefined threshold values, the Arduino processes the d and adjusts the motor speed accordingly using a

PWM (Pulse Width Modulation) signal. A motor driver (L298N or MOSFET-based circuit) is used to control the DC motor

efficiently. This automation eliminates manual intervention, optimizes energy consumption, and enhances system performance.

The proposed design is cost-effective, easy to implement, and adaptable to various applications where temperature-dependent

motor control is required
