Abstract—This paper presents design of an efficient air conditioning control system that decides the number of air conditioning units to be operated based on the occupancy of a building. The objective of the research was to develop an automatic system using inexpensive electronic components and basic control methods in order to reduce electric power wastage in schools, colleges, offices, and homes. In this research, several experiments have been conducted to determine the optimum parameters for designing a cooling control set-up. The hardware implementation of the smart control system is presented and its performance is assessed. The proposed smart system was installed in building NJ10 at University of Jeddah, Jeddah, Saudi Arabia as a pilot project. As per the observations, energy consumption and cost can be reduced by a considerable amount, making the system efficient, when the proposed set-up is installed.
