摘要
传统的干湿球湿度计结构简单。温度、湿度测量两用。具有一定的准确度 ,寿命长 ,造价低 ,在各类实验室得到广泛的应用。但干湿球湿度计需对温度测值换算才能得到相对湿度值。现介绍一种根据干湿球湿度计原理 ,采用单片机和集成温度传感器组成的数字式湿度计的设计方法。阐述了它的硬件电路结构 ,以及单片机软件的工作流程。通过对相对湿度与干湿球温度间的数据分析 。
The traditional psychrometer is widely used in all kinds of laboratories. The advantages of it are as follows: for one thing, the structure of it is very simple and it can be used in both temperature and humidity measurement ; for another thing, it has a certain degree of accuracy ; Besides, the life\|span is long and the fabrication cost is low. However, only by converting the acquired temperature can we get the relative humidity. This paper introduces a new design method based on the principles of psychrometers. The method adopts the idea of hygrometers made up of single\|chip computers and temperature sensors. What's more, this paper also describes the hardware circuit structures and the principle of operation of single\|chip computers. By analyzing the data of relative humidity and temperatures, it expounds a simple method used in the calculation of relative humidity.
