温度测控系统的设计：

利用ADC0809采用中断式设计一个温度测控系统，在LED数码显示器上显示温度值，并对温度进行测试和控制，当检测温度到达温度上限60℃时开风扇（即开启电动机），低于下限30℃时关闭风扇，LED上的显示内容为：XX ℃（采用十进制显示）。-Temperature measurement and control system design: the use of the ADC0809 interrupt type design of a temperature control system, the temperature value displayed on the LED digital display and temperature test and control the fan on when the detected temperature reaches the temperature limit of 60 ° C (open motor) below the lower limit of 30 ° C, turn off the fan on the LED display content: XX ° C (decimal display).
