Design of smart home control system based on ZigBee Technology

Abstract. Based on the ZigBee technology, a hand-held portable intelligent home controlled termi-nal is designed on the basis of STC12C5A60S2 MCU, and make a detailed hardware design with floor control module. Main ZigBee (coordinator) module is connected with the handheld terminal and salved ZigBee (rounter) module communicate with the underlying chip so that lighting system, window treatments, fans system and air conditioning system are controlled. This paper focuses on designing closed-loop system by curtain and fan control systems. According to light intensity and real-time temperature, the system control brightness and temperature inside the home. The set of intelligent home model has been set up and run normally, passed the test system better able to communicate within 15m,and system is easy to use and has good practicability. Smart Home is a comprehensive use of power automation technology, network communication technology, automatic control technology, integrated home systems. Compared with traditional home, whether living comfort, convenience of work are promoted to a higher grade. Over the wire-less network to a variety of devices in the home (lighting systems, window systems, air condition-ing systems, fan systems, security systems, etc.) combine together by the terminal controller inte-grated management, in order to achieve safe, comfortable and eco-friendly living environment [1]
