摘　　要：介绍一种性能稳定、灵敏度高、体积小、基本不受温度影响的高分子电容式湿敏器件及其信号处理,依据此方案可制备精度为±3%RH的直读式相对湿度数字显示仪表,可用于湿敏控制或界限警装置.A relative humidity sensor is studied which has the advantages of high tem-perature stability and sensitivity and small size. Two kinds of signal processing schemes(hardware and software implementations) are provided which can be used to measurerelative humidity with precision of ±3% RH and used as a humidity control or criticalalarm system.
