大气湿度的测量--由HS1101构成的湿度检测电路图3． 测量电路输出的模拟电压通过U18 接口转化为数字信号输入PC机，这一AD 转换功能由U18 硬件平台提供，U18软件内的U18 软件功能模块实现硬件接口的驱动和通信及信号处理等基本功能的实现。
4． 如图所示，当大气湿度变大时，HS1101两端的电容变小，利用TLC555产生的震荡频率变大，在TP4端可观察。
5． 经过数据采集和软件处理，最终形成与湿度变化大小成一定关系的的线性频率。
-Measuring atmospheric humidity- humidity detection circuit constituted by the HS1101 3. The output analog voltage measurement circuit U18 via the interface into a digital signal input PC, the AD conversion function is provided by the hardware platform U18, U18 U18 software modules within the software driving the basic functions and the signal processing and communications hardware interface of achieved. 4. As shown, when the atmospheric humidity increases, the capacitance across the small HS1101 using TLC555 oscillation frequency becomes large, the terminal can be observed TP4. 5. After data acquisition and processing software, eventually forming into a certain size with humidity changes the relationship between linear frequency.
