空气湿度报警器，顾名思义，是用来测量空气中的湿度的仪器，他通过一个湿敏电容和一个频率输出电路对空气湿度进行检测，把湿度变化转变成频率输出。再通过单片机把输入的频率转化为湿度百分值并通过LCD显示出来，使人可以通过显示清楚地看到空气的相对湿度。在单片机编程时可以预先设定一个限定值，当环境湿度达到设定的湿度值时电路报警，同时发光二极管变亮，达到湿度报警的目的。-Air humidity alarm, as the name implies, is used to measure humidity in the air apparatus, he humidity through a capacitor and a frequency output circuit for detection of air humidity, the humidity changes in the frequency of the output into. Through the single-chip frequency of the input into a percentile and humidity through the LCD display, one can clearly see through the display of the relative humidity of air. Single-chip can be programmed in advance to set a limit value, when the environmental humidity to achieve set alarm circuit humidity values, while LED light changes to achieve the purpose of humidity alarm.

下面的函数LoadBmpFile，其功能是从一个.bmp文件中读取数据(包括BITMAPINFOHEADER，调色板和实际图象数据)，将其存储在一个全局内存句柄hImgData中，这个hImgData将在以后的图象处理程序中用到。同时填写一个类型为HBITMAP的全局变量hBitmap和一个类型为HPALETTE的全局变量hPalette。这两个变量将在处理WM_PAINT消息时用到，用来显示位图。该函数的两个参数分别是用来显示位图的窗口句柄，和.bmp文件名(全路径)。当函数成功时，返回TRUE，否则返回FALSE。-The following function LoadBmpFile, its function is from a. Bmp file to read data (including the BITMAPINFOHEADER, palette and the actual image data), its stored in a global memory handle hImgData, this hImgData will in the future plans used as treatment procedures. At the same time, fill out a type of global variable HBITMAP HBITMAP HPALETTE and a type of global variable hPalette. These two variables will be used for treatment WM_PAINT message, used to display bitmaps. The function of two parameters are used to display the bitmap handle of the window, and. Bmp file name (full path). When the function is successful, return TRUE, otherwise return FALSE.
