| Abstract: | The microhumidity sensor are designed based on micro-machining technology . A temperature compensation method of the humidity sensors based on differential circuit is introduced. Experiments show that the humidity sensor has semi-logarithmic linearity. The output of humidity sensors is less than ±4 % RH when environmetal temperature is 10～40℃. |
