Abstract

Today, the energy consumption issue is critical because it is one of reasons causing increases in global warming. Greenhouse gas emissions and global environmental effects result in a high energy consumption. Because of its high electricity capacity and unregulated usage time, the air conditioning system is the biggest factor of energy consumption for electrical appliances in Malaysia. In order to automatically regulate and maintain the ambient temperature, the project therefore aimed to create an automatic temperature controller for air conditioner. In addition, this automated temperature controller reduced energy consumption and decreased electricity cost for users. Additionally, this temperature controller has an automatic temperature control feature with use on basic air conditioner. Electrical components like the microcontroller and temperature sensor were used in this project to measure ambient temperature before controlling the system of air conditioning temperature. The experiments are performed and ambient temperature data is collected following the development of the controller. The results of the experiment using the Fuzzy Logic Control algorithm for the automatic temperature controller show that the energy consumption of the air conditioner is more effective with 7605 Wh, compared to 7991.1 Wh of the automatic temperature controller using If-else algorithm and 9360 Wh of the manual temperature controller. The findings show that this Fuzzy Logic Control algorithm automatic temperature controller is the lowest electrical consumption and the most economic assessment of the experiment. In conclusion, an automatic temperature control device has been developed that displays the ambient temperature and air conditioner temperature where this system can monitor and regulate the temperature for the sake of energy efficiency.
