| Abstract: | The status of humidity measurement and the basicprinciples of microwave humidity measuring were introduced,and the hu- midity measuring instrument was designed. The humidity detection algorithm which is unrelated with density was established, the linear re- lationship between microwave and humidity was set up, and a fast high precision measurement to measure the attenuation and the phrase shift was designed. The experimental results proved that it can measure the humidity. |

| Keywords: | microwave humidity measurement density-independent |
