1、工作原理
Principle
电阻式湿度传感器测量相对湿度方法:不同的相对湿度对应着湿度传感器不同的复阻抗(Z,
非纯电阻 R)输出;相对湿度(%RH)与湿度传感器输出的复阻抗的对数值 log10(Z)呈线性关系;
即:%RH~log10(Z)成线性关系。
Measuring: Different relative humidity correspond to different impedance of humidity sensor (the
symbol is Z, not R). There is linear relation between the relative humidity (%RH) and the impedance’s
logarithm of humidity sensor log10(Z), that is %RH~Log10(Z).
