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.

Gives you a brief idea of zigbee.

论述了小波包分解及其能量谱处理发动机连杆轴承故障的原理与方法, 结合传统断火诊断法的思想,应用小波包能量谱直观地识别出故障的特征频带, 并进行量化分析, 结果证明了这种方法比传统的付立叶分析方法具有更大的优越性及现实的应用价值(Discussed and wavelet packet energy spectrum processing engine connecting rod bearing failure principles and methods, combined with traditional diagnostic methods ideas off the fire, the application of wavelet packet energy spectrum visually identify the fault characteristic frequency bands and quantitative analysis, the results show this method than the traditional Fourier analysis method has advantages and practical application value)
