此次设计主要能够完成对空气湿度的测量监控和数据处理以及显示报警功能的实现，可以通过键盘输入参数来设置系统得目标值和报警值，通过LCD来显示当前相对湿度值和键盘输入的目标值、报警值。当当前相对湿度值达到某种程度时，作出对应得驱动和报警。-The design is mainly to complete the measurement of air humidity control and data processing and display functions to achieve the alarm can be set through the keyboard input parameters have to target and alarm values ​ ​ of the system, through the LCD to display the current relative humidity value and the keyboard input of the target value, alarm value. When the current value of the relative humidity reaches a certain degree, to be driven and the corresponding alarm.
