Abstract In this paper, the design of smart home control system composed the advantages of low power consumption, low cost, excellent performance, and high practicability, etc. This system take AT89S52 microcontroller as the core, Bluetooth for communication between the microcontroller and a PC(server-side), Internet for remote communication. This system studied the application of the sensor in detect the indoor temperature and examine the concentration of combustible gas. This project designed the smallest single-chip control system module, smart switching window module, DS18B20 digital temperature sensor module, Bluetooth communication module, fire alarm module, and microcontroller to PC-server communication module. This design achieved a lot of functionality, such as real-time detect the indoor temperature and the concentration of combustible gas, window smart open and close, fire alarm intelligent alarm, smart devices automatic control as well as remote control. This paper introduces the working principle of the system and the method to realize remote control, detailed descript the schematic design and PCB design and summarizes the design, built an prototype to experimental debugging and performance testing. As debugging, all modules of the circuit board worked properly, the function to achieve the desired effect, the project meet the design requirements and achieve the design objective.
