Abstract

This project focuses more toward conservation of energy. This project is about improvement made to an ordinary AC ceiling fan by integrating it to the microcontroller as the main system so that it can use temperature sensor as the main speed controller. The fan will intelligently interact with the surrounding temperature change to control the speed of the fan. When in cold condition the speed of the fan will be in slow motion but still capable to cooling the room area. Then when the weather is hotter the speed of the fan will increase to the most suitable speed to maintain the room temperature area to make the user always feel comfortable and easy. User can choose whether to control the fan manually or automatically. In this project the saving energy aspect focuses at night. As we know at night temperature is gradually decreasing from 12.00 pm until 7.00 am. Regularly user will set a certain speed to the ceiling fan at night before they get in to the bed. The power use by the fan is constant, since mostly we will not get up while in sleep time, thus we will not decrease the power consumption by decreasing the speed of the fan. With universal Smart Fan Controller AC fan concept power can be reduced a lot since the temperature at night is gradually decreasing. So the fan speed is also decreasing means the power consume by the fan is reduced. Intelligent aspect of the project is when the temperature sensor can read immediate surrounding temperature and feed it to the microcontroller. Then the fan will rotate according to signal sent by microcontroller. Due to the intelligent aspect of this system the energy consumption could be reduce from the usual type of ceiling fan. From the results of the project it is proven that the hardware can reduce the power consumption up to 27%. So there is high improvement in term of energy saving after installation of the device. Beside the energy reduce it's improve the quality of sleep at night since the device control the speed of the fan and user will get the most suitable ambient temperature at night during sleep according to the temperature read by the temperature sensor.
