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.

SHA加密算法是目前广为应用的重要加密方法之一。而SHA
SHA加密算法是目前广为应用的重要加密方法之一。而SHA-1 生成 160 位的消息摘要，虽然执行更慢，却被认为更安全。明文消息的最大长度可达到 264 位。下面是网络上流传的SHA算法，我们自己调试了一下，已经通过。现把主函数和算法函数贴出来。-SHA encryption algorithm is an important widely used encryption methods. And SHA-1 generates the message digest 160, although more slowly, but think more secure. Explicit messages the maximum length could reach 264. The following is a network spread SHA algorithm, debugging a bit of our own has passed. Are the main functions and algorithms function posted.
