Designing Switching System for AC Powered Appliances Using Microcontroller

This paper describes the first phase of the development process of this project. There are two phases involve in this research work. In the first phase, PROTUES simulation tools were used to design, study and analyze the proposed research work. Results from the simulation will be use as reference to re-design and develop the real-time hardware-based system. In the second phase, the hardware will be developed based on the study and analysis carried out in the first phase. The developed hardware will be integrated to a stand-alone source powered via photovoltaic technology. This will be an added advantage to this system because it will be able to operate without having to connect to the electrical network system. Furthermore, the system is integrated to light dependent resistance and negative temperature coefficient sensors to automatically operate the system based on the sensors characteristics.
