摘要
介绍了相对湿度传感器HS1100/1101的特点、特征参数及其与555定时器构成的无稳态振荡电路;在特定电路参数下,通过多次实验测量,分析空气中的相对湿度与电路输出频率的关系,最后给出湿度测量子程序的流程图。
In this paper the features and characteristics of relative humidity sensor HS1100/1101 and the astable circuit of 555 are introdu ced. After experimentation, the relationship between relative humidity and frequ ency is found out under the particular circuit parameters. Ultimately, the flow chart of subprogram for humidity measure is shown.
