通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。-Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.

仪器仪表键盘显示模拟系统，用AT89S52芯片作为系统的CPU，控制系统的按键及显示器部分。用8路同相三态双向总线收发器74LS245芯片驱动LED。4X4矩阵键盘作为系统人机交互的重要部分，用于向单片机应用系统输入数据或控制信息，设计4X4矩阵键盘分别对应键码“0-F”。系统可以实现的基本功能包括开机LCD液晶屏幕显示“大专05电子信息X班XXX毕业设计”信息；按下任意一个按键，LCD液晶屏幕显示相应按键的信息。在基本功能的基础上还增加了一个扩展功能，即增加一个LED数码管同步显示相应键码-Show the simulated keyboard instrumentation systems, using AT89S52 chip as a system CPU, system control buttons and display parts.
