Fan Speed Control System Temperature Sensor LM35 Interfaced

Abstract

This project presents a Fan Speed Control System that automatically adjusts the speed of a fan based on the surrounding temperature, utilizing the LM35 temperature sensor. The LM35 is an analog temperature sensor that provides a linear output proportional to the detected temperature. It is interfaced with a microcontroller (such as Arduino or any other MCU) to read the temperature data. The microcontroller processes this data and adjusts the fan speed using Pulse Width Modulation (PWM), ensuring efficient cooling. The primary objective of this system is to enhance energy efficiency by regulating the fan speed according to temperature changes, thereby reducing power consumption when full speed is not necessary. This project is ideal for applications in temperature-sensitive environments, such as electronic device cooling, HVAC systems, and home automation. The system offers a cost-effective and reliable temperature-based fan speed control solution, providing real-time adjustments and contributing to better thermal management.
