Subhashini, Raed Abdulla, Thinaga Raj R Mohan School of Engineering, Asia Pacific University of Technology and Innovation (APU), Technology Park Malaysia, Bukit Jalil, Kuala Lumpur, Malaysia Article Info ABSTRACT Article history: Received Dec 27, 2017 Revised Jul 14, 2018 Accepted Sep 18, 2018 This paper aims to develop a wind energy harvesting system to charger an electronic device of 5V during traveling period from a place to another. Upon the situation faced by the two wheeler depending on the conventional power socket, this system was constructed to overcome the dependencies of power since the natural energy can be harvested to produce an electrical energy. The power storage unit system was done by integrating supercapacitor to storage the electrical energy hence an arduino microcontroller was been integrated with supercapacitor which able to display the percentage and voltage stored in the supercapacitor. The maximum speed of the geared DC generator is 1297 rpm and based on the testing carried out, it was observed that the maximum voltage produce at 1297 rpm able to produce 17V which sufficient to power up the entire system as it required 5.3V for operating. Besides, the system was converted into acrylic board since the system are to be implemented on two wheeler hence the acrylic board was design based on the conform ability of the user. In a nut shell, the functionality of the entire system was successfully achieved based on the objectives and overcoming the drawback from past research work.

Some studies has stated that, availability of oil will vanish in another 15 decades and the global energy demand will increase three times by the year of 2050. Considering the impact for the future generation, numerous studies has been carried out emphasizing on sustainable development and efficient energy conservation. Many inventions has been made to utilize the renewable energy resources for various applications [1]. The two important factors regarding renewable energy are energy management and saving energy [2]. Most commonly harnessed renewable energy are wind, hydro and sunlight. Among the three gifts of mother-nature, power produced from wind are known to be reliable energy because anything which moves produces wind besides naturally generated wind. Moreover wind energy does not cause greenhouse effect during the process of conversion from mechanical to electrical energy. Wind energy is the energy present in moving air. Past studies has been focused on harnessing the wind energy for large scale applications such as to produce electricity for rural areas, running a windmill and pumping water from a well. Recent studies on the other hand are being focused on harvesting wind energy for smaller scale portable applications. In such application, smaller turbines are designed in such manner where it can be mounted on any type of land vehicle with adequate storage capacity to power up most of the electronic devices available in the market.
