“Automatic Temperature control fan”

This project presents the design and implementation of a temperature control fan system that automatically adjusts its speed based on the surrounding temperature.The primary objective is to provide an energy-efficient solution for maintaining optimal environmental conditions, especially in areas where temperature fluctuations can affect comfort, safety, or equipment performance.The system utilizes a temperature sensor (such as LM35 or DHT11) to continuously monitor ambient temperature.The sensor data is processed by a microcontroller (e.g., Arduino), which controls the fan speed using pulse-width modulation (PWM) or relay switching mechanisms.The fan activates or increases its speed proportionally when the temperature exceeds a predefined threshold, but slows down as the temperature decreases.This intelligent fan system is applicable in-home automation, electronics cooling, greenhouses, and other temperaturesensitive environments.The project demonstrates the effective use of sensors and automation to create a responsive and energy-saving cooling solution.
