我有更好的答案
主要是温度传感器和程序编写！报警可以用蜂鸣器，灯闪烁！
采纳率：50%
参考一下，很简单
你好！采用什么传感器呢
温度传感器DS18B20
需要portel文件

STC89C52单片机，用C语言编温度报警器的程序
急求一份用keilc51
c语言编的程序 ，单片机实习急用。。。用的是STC89C52单片机，温度报警器，万年历，什么都可以啊
有电子时钟的最好了~~能外加实验报告就更好了
我有更好的答案
温度报警就用外部中断不就行了？和18b20连接万年历就是利用定时器就可以了吧。在加一块液晶屏用来显示。具体的应该网上都有你可以搜一下。 我帮您搜了一个万年历的程序一、 阳历算法具体算法见函数void get_solar_day_date(void)，这样阳历日历的星期排法就确定了。表1：变量定义：Public:Unsigned int temp_total_Unsigned char gc_solar_calendar_Unsigned char gc_solar_calendar_Unsigned char gc_solar_calendar_Unsigned char gc_lunar_calendar_Unsigned char gc_lunar_calendar_Unsigned char gc_lunar_calendar_Unsigned char start_day_of_week；说明：函数get_solar_day_date(void)的输入变量：gc_solar_calendar_year和 gc_solar_calendar_month输出变量：start_day_of_week和temp_total_dayVoid get_solar_day_date(void){unsigned char temp01;/*------calculate what day is the day of the current month and year.
