Room Temperature based Fan Speed Control System using Pulse Width Modulation Technique

Abstract

This paper presents the design and simulation of a novel fan speed control system based on room temperature using Pulse width Modulation Technique. The duty cycle is made to vary according to the room temperature and the fan speed is controlled accordingly. This paper elucidates how the autonomous speed control of fan is done based on data from the temperature sensor. The design proposed here is appropriate according to the modern lifestyle. The simulation of the system has been done on Proteus Professional Software v 8.0 and the various graphs showing relationship between temperature and different parameters have been plotted in MATLAB R2013a v8.1 to validate the accuracy of the system.
