摘要
根据由焓湿图总结出的相对湿度计算公式，用ＡＤ５９０作为温度传感器，结合ＭＣＳ—５１单片机编程，提出了用双精度干湿球原理查表法，对无风条件下的冷藏库湿度测量的软件方案。通过实践检验，效果良好．
According to the relative humidity measurement formula concluded from enthalpy humidity chart, and adapting AD590 as temperature sensor, and combining the program of MCS-51 single chip micro-computer and looking up the table of double precision for drymoisture ball, a software scheme is propoSed for the humidity measurement of cold storage under the condition without wind.The effect is good through practical check.
