Temperature Based Fan Speed Controller Using Arduino

Abstract

We all know that we are moving towards the automation. So basically in this project we will be controlling the speed of the fan according to the temperature of the surrounding .The system will get the temperature from the temperature sensor and it will control the speed according to the temperature set by the user. It also uses the LCD display to display temperature from – 55 to 125c and speed of the fan in percentage. The Arduino device plays a major role as the processing part. If the surrounding temperature is greater than set temperature fan turns on else vice-versa. By this project it is helpful to save the energy where saving of energy is one of the most important thing we are facing load shedding. KEYWORDS: Arduino UNO, LM35, LCD display.
