![]() ![]() The fan will be used to reduce the temperature of a room at certain level. ![]() This project presents the designs and the simulation of a DC fan control system based on room temperature using pulse width modulation technique and temperature sensor namely LM35 with Arduino Uno Microcontroller. Hence, the objectives for this project are to enable the electric fan to automatically change the speed level according to temperature changes and develop an automatic fan system that can change the speed level due to the environment temperature changes. So, the automatic fan system that automatically changes the speed level according to temperature changes is recommended to be built for solving this problem. Othman* School of Electrical & Electronic Engineering, Universiti Sains Malaysia, 14300 Nibong Tebal, Pulau Pinang, Malaysia *Ībstract- Most human feels the inconvenient about changing the fan speed level manually when the room’s temperature changed. Design and Implementation of Automatic Room Temperature Controlled Fan using Arduino Uno and LM35 Heat Sensor Nur Afiqah Junizan, Amirrudin Abdul Razak, Bohendiran Balakrishnan, W.A.F.W. ![]()
