Abstract

Automatic control plays an ever-increasing role in a person's lifestyle. Automatic control is a vast technology area with a central focus on developing control strategies that increase productivity when applied to a system. A distinctive feature of automatic control is that it reduces the number of people-operators. One such gadget is a fan. Fans are usually available with variable speed, depending on the requirements of the set speed. Typically, at high temperatures, the fan runs at high speed, and at lower temperatures, the fan runs at a lower speed. This is done manually with the help of a human. This article proposes a solution for automatic fan speed control. A circuit with LM35DZ temperature sensor, PIC16F877A microcontroller, brushless DC motor and several electronic components is designed and implemented for automatic fan speed control. An LCD display is used as an optional feature to display temperature and fan speed. Finally, the developed system circuitry was tested many times and worked very well.
