Electricity is part of everyday life. Lots and lots of gadgets, run on electricity are made to provide us the comfort. One such gadget is fan which provides us with comfort by circulating air.The fans are generally available with speed control. Depending on the requirement we set the speed. Usually, when the temperature is high we set the fan at high speed and at lower temperatures we operate the fan with lower speed. This is done with human involvement.Through this project we are providing an automatic solution. Our system detects the temperature and sets the fan speed accordingly. As an additional feature we would like to provide the temperature and the current setting of fan speed on a display.
