Nowadays, automation system becomes the best solution to overcome human problem which is always forget to switch off the electrical appliances. As we know, there are a lot of types of the automation system which is too expensive and difficult to use. For that reason, an automation system at low cost is built where; user can also program the automated system by their own. The purpose of this project is to design an automation system that can be used to switch ON, OFF and get know STATUS of the electrical appliances by using personal computer. This project focusing developing an automation system with Zigbee wireless technology which is controlled by programmable interface controller (PIC18F14K50). This overall project is divided into two parts. The first part is concern on the hardware development where all electronic components are connected on a single board. Personal computer is the input component while fluorescent lamp and fan are the output component where it’s all controlled by controller circuit. Zigbee is a new technology, which has at its centre the goal of eliminating wired connections between home appliances and personal computer. Instead of connecting with wires, every appliance has small transmitters or receivers. The second part is base on software programming to operate the hardware structure. There two types of programs are used for this project. C language is the program used for PIC18F14K50. C language assembles using CCS C Compiler to get the hex file. The hex file loaded into PIC memory using PIC kit 2 burners. C # is another program that used for create GUI for personal computer .In order to achieve better automation system, the security system can be added to this project where more sensor and load can be connected to the PIC serial port. As the result, the PIC capable to control the whole operation of this automation system.
