单片机课程设计温度报警器

A. 单片机温度报警器没有超值也报警

温度报警器就是需要温度传感器不停地对监控的对象进行检测
单片机报警模块是指的主要功能部分采用成品的模块，所以比较容易制作。单片机报警模块有遥控设定防盗、遥控关闭防盗自动锁定引擎和防抢劫等功能。单片机报警模块电源接通后按动遥控器防盗设定键A键，HY988A I/O端输出跳变高电平经D3使T3导通HY-5高响度喇叭发声作为回应信号。单片机报警模块输出端输出高电平经R1为T1提供基电流，这时如果HY966受到轻微震动，其输出端输出高电平脉冲使T1导通。单片机报警模块T1的导通使C1瞬间充电至+5V左右，此电压高于比较器参考电压，比较器反转输出高电平经 A1B 缓冲后驱动继电器吸合、HY-5喇叭报警。单片机报警模块此后如 HY966 不在受到震动C1经R4缓慢放电，当C1上的电压放电至低于比较器参考电压时，比较器反转输出低电平，继电器释放、报警停止，继续警戒状态。

B. 单片机温度报警系统

C. 单片机多路温度巡回报警器

1.首先确定自己有没有能力做。
在学校学习的，上课还听的，还有点上进心的，那不急还有半年慢慢做，单片机学学也就2-3个月的事情，不懂问老师，一步一个脚印学下去，悟性好的，1个月足够做出个毕业设计了。曾有个同学我带他做毕业设计，本来是混日子的，一个月的时间久把毕业设计做出来了，好像也是温度计。如果有什么不懂的可以问我；
混日子的同学，很懒，有那么点钱，没什么出息的，买设计吧，我给你做全套，价格优惠。

D. 单片机温度报警器的温度上下限按键调控的C语言程序怎么编

温度报警器就是需要温度传感器不停地对监控的对象进行检测，例如pt100温度传感器，pt100传感器是不同温度下，阻值会不同，在同一温度下，阻值是相同的。根据这个原理通过电路转换成电压，然后模拟量转换成数字量输入到单片机，单片机根据读取到的电压值判断实际温度值，然后根据设定的报警值比较，如果超过 就进行报警动作。
在实际设计过程中那个报警温度的设定，可以直接对那个变量进行加减的，例如
void actfuntion(unsigned char temp)
{
temp++;
}
然后在检测到按键有电平跳变的时候，就调用这个含参子函数对定义的温度设定值进行加操作，减操作也是一样，还可以在调用的后面进行最大值或者最小值的判断。
如果觉得这样一下一下的按太麻烦了，可以对按键进行长按连续触发进行判断，就是在定时器里进行判断按下时间，然后不停的调用这个子函数。
当然这个设定值是需要考虑掉电保存的，或者是按键保存。可以在设定好温度值之后，在按下其他的按键，进行把温度设定值 保存到单片机内部eeprom就可以了，不需要保存太多数据的情况下，现在市面上很多单片机都有的内部eeprom就够用的了，不需要进行外部扩展。
然后在单片机上电，也就是主函数的开头进行读取eeprom中保存的设定值。

E. STC89C52单片机，用C语言编温度报警器的程序

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_day;
Unsigned char gc_solar_calendar_year;
Unsigned char gc_solar_calendar_month;
Unsigned char gc_solar_calendar_date;
Unsigned char gc_lunar_calendar_year;
Unsigned char gc_lunar_calendar_month;
Unsigned char gc_lunar_calendar_date;
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_day
Void get_solar_day_date(void)
{
unsigned char temp01;
/*------calculate what day is the day of the current month and year. Mon~Sun?---*/
/*条件初始化二次，减少运算数据量. temp_total_day 是int型变量*/
start_day_of_week = 2; temp_total_day = 0;calculate_temp = 1;
if(gc_solar_calendar_year > 99)
{start_day_of_week = 6;calculate_temp = 100;}
for(temp01 = calculate_temp; temp01<gc_solar_calendar_year; temp01++)
{ if(temp01%4 == 0){start_day_of_week +=2;temp_total_day += 366; }
else {start_day_of_week +=1;temp_total_day += 365;}}
for(temp01 = 1;temp01<gc_solar_calendar_month;temp01++)
{ switch(temp01)
{case 1,3,5,7,8,10,12: start_day_of_week +=3;temp_total_day +=31;break;
case 2: if(((gc_solar_calendar_year%4) == 0)&&(gc_solar_calendar_year != 200))
{start_day_of_week +=1; temp_total_day +=29;}
else {start_day_of_week +=0;temp_total_day +=28;} break;
case 4,6,9,11: start_day_of_week +=2; temp_total_day +=30; break;}}
start_day_of_week %=7;
/*-end of calculate what day is the day(Mon~Sun?) and total day --*/
}

二、 阴历算法
200年需要200 × 2 = 400个字节，构成阴历压缩数据表lunar_calendar_month_table[]如下
const char lunar_calendar_month_table[]={ //从阴历年1900年到2100年
/*the total day of each month pointer */
月份 1 2 3 4 5 6 7 8 9 10 11 12
闰年 31 29 31 30 31 30 31 31 30 31 30 31
非闰年 31 28 31 30 31 30 31 31 30 31 30 31

/* from 1901~2100*/
/* (0110)110000001001 (0110)leap month,110000001001
lunar month total day: 1:29 0:30*/

以上就是万年历的完整算法。它首先计算出对应阳历月第一天对应是星期几，然后根据数据压定，确定对应的阴历日期；而阴历节气，则有条件规律算法实现。

F. 基于单片机的温度检测报警器

由
温度传感器
AD0809
采集信号得到与之对应的
模拟信号
。A/D转换电路对处理之后模拟信号数值化，将模拟信号转换成数字信号。再由集成运放LM741对微弱的电信号进行放大处理，输出电压U0=2.732-UI，输出电压U1>2.732，是一个反向电压。反向
比例运算电路
，其输出电压
UO=-2UI，U0是一个正电压。再通过单片机（8951）对信号进行读写操作，经单片机处理后由
七段数码管
显示。并通过键盘输入模块向单片机设定高温
临界温度
。当前环境温度若超过设定的高温临界温度，由单片机发出报警信号并驱动继电器使风扇电机转动。

G. 想用单片机开发一个温度湿度警报器，当温度湿度过高时，触发警报。需要哪些东西

单片机最小系统就不用说了吧 就是能让单片机工作起来 然后是湿度的传感器 和报警器 这些分别与单片机的某些引脚连接 接着就是单片机的编程 这个东西不大 用54应该能实现了 编程也就是说 当开启电源后 传感器开始检测 写一个报警的值 当达到这个值时 单片机发送个电平给报警器让起工作 报警.

H. 温度报警器，用单片机实现，温度范围有用户设定，要显现出来并与实时温度相比较进行报警， 怎么实现呢

用18b20温湿度检测温度的值，，然后和你设定的温度值比较，如果超出了范围就用给蜂鸣器赋值，触发报警。。。
