  • 智能温度检测控制系统设计
    说明:  首先它能显示环境的温度并能设置上下限阀值,这是最基本的功能,系统上电的时候显示的是当前环境温度和设定的温度阀值,我们可以通过按键来修改温度上下限阀值。(First of all, it can display the environment temperature and set the upper and lower limit threshold, which is the most basic function. When the system is powered on, it displays the current environment temperature and the set temperature threshold. We can modify the upper and lower limit threshold by pressing the key.)
