Abstract: Humidity sensor is a sensitive device that can sense environmental humidity parameters,which is widely used in meteorological detection, agricultural planting, industrial manufacturing, and collection storage, etc. Humidity-detection characteristics are mainly affected by humidity-sensitive material, detection electrode, packaging, and detection-circuit design. Among them, the material properties and structure characteristics of the humidity sensitive material are the most significant factors to affect the humidity-sensing performance, which are also the hot research topics in this field. The mechanism of humidity sensing and the materials’ chemical characteristics and structure properties are firstly discussed. Then comes the introductions of humidity sensors’ detecting parameters along with optimizations and statements on nanosclae humidity-sensitive materials in detecting application. The common-used packaging scheme and detection-circuit design of humidity sensor are finally reviewed.

Key words: humiditysensor, humidity-sensitivematerials, packaging, testingcircuits
