自用电脑温度报警

描述: 最近发现电脑风扇有时候不转!散热口那会烫的厉害!拆开后盖后可能是风扇接线接触不良!写个程序监控一下CPU的温度! 1. windows控制台程序. 每2分钟采一次温度数据,如果温度高于60,70,80,90(不大可能)时分别响警报声2,4,6,8次:温度高于60,70时采集频率加倍,控制台打印字体显黄色:变成1分钟采一次,高于80的时候30秒采一次,控制台打印字体显示红色: 2. 加入windows自启动. 代码: 新建temptest.cpp.加入如下代码. 报警声用cout<<&q

时钟+温度+遥控设置，综合时钟例子

时钟+温度+遥控设置,综合时钟例子6月30日到手的二手单片机开发板,今天做个综合的时钟例子,包含代码和仿真.做个近期的学习总结. 按独立键盘K1和红外遥控的EQ为设置键.按独立键盘K2和红外遥控的VOL+为加键.按独立键盘K3和红外遥控的VOL-为减键. 手摸温度传感器,当温度超过 34℃ 的时候点亮LED灯,模拟启动的设备. 程序有很多细节没有优化,主要是学习,lcd1602显示,独立建扫描,红外遥控,ds1302时钟芯片,ds18b20温度传感器. 实时时钟综合应用,源代码和仿真下载http

使用erlang 建立一个自动化的灌溉系统（1）准备工作

1. 你需要一台电脑作为监控系统的控制中心.(我直接用了垃圾机器装了debian 系统) 2. 安装一个你喜欢的编辑器 .(我个人比较喜欢wingide ,主要我需要写点python 代码) 3.一台树莓派.(这个资料很多,我们客户端的python 代码都在上面实现) 4.到github 上下载最新的erlang 代码和yaws 直接编译源码.(yaws 安装会有些问题,你可以参考http://www.cnblogs.com/codewarelock/articles/4781656.htm

后台的网页设计

温度报警系统设计目标:移植到arm-linux开发板 1.伪静态html+cgi+javascript 动态时钟设计+动态文本+可视化动态效果(javascript操作数据) 优点:可以实现局部大多动态效果,且javascript脚本会实时处理数据,能在不刷新的情况下,维持数据操作,在设计功能上,能提供除显示状态功能外的设置功能但重要的缺点,无法读取本地文件(1.Active插件不可用2.cgi读取本地文件,不能实现动态读取,每一次读取请求会被当做执行一次cgi程序,造成页面数据丢失),无法
