摘要
研究基于单片机的干湿球测湿方法 .通过对湿度、干球温度、干湿球温差三者关系的分析 ,提出一种把曲面问题转化成曲线问题的计算方法 .本方法不仅计算简便 ,而且计算准确 ,如计算结果四舍五入保留整数 ,则与湿度查算表数值完全吻合 .实验表明 :应用此方法的单片机测湿系统 。
Damp bulb method based on singlechip is studied.The relation of humidity,dry-bulb temperature and damp bulb temperature was analysed and one calculation method which transforms surface problem into curve problem is brought up.This calculation method not only is simple but also has high veracity. The result of test indicates that the humidity measure precision depends on mainly the temperature measure precision.
