主要由AT89C52主控制器、18B20温度传感器、1302时钟芯片、1602液晶显示屏以及按键控制系统组成。本系统以单片机C语言进行程序的编写，由于C语言与单片机底层结合，使程序设计的逻辑关系更加简洁明了。此程序直接在Keil软件编译程序，利用Proteus进行仿真调试，方便修改调试。-Mainly by the main controller AT89C52, 18B20 temperature sensor, clock chip 1302, 1602 LCD screen and button control system. This system microcontroller C language procedures for the preparation, because the underlying microcontroller C language and combine to make programming more concise logical relationships. This software program directly in the Keil compiler, using the Proteus simulation debugging, easy to modify debugging.
