Traditional manual monitoring is gradually due to the presence of a lot of the shortings of intelligent electronic monitoring replaced. Designed primarily to do the work of the following aspects: First, determine the overall system design, including its functional design。 position and working principle。 including hardware circuit and measuring principle 。 microcontroller choice。 debugging and emulation, including hardware emulation and software simulation. In this context, our expertise and background, intelligent temperature control system design and experiments. This system is an automatic feedback control system. STC89C52 microcontrollerbased control unit, temperature sensor DS18B20 temperature control system. Main modules: the main control unit module, the temperature detection module 1602 LCD module, the key input module, the buzzer alarm module, temperature control module. Key words: STC89C52 SCM DS18B20 1602 LCD main control unit II 目錄 摘要 .........................................................................................................................................................................
