摘要
在研究粮食的湿度-电阻特性和温度-电阻特性的基础上，设计了采用对数放大器和有自动温度补偿功能的信号处理电路，构成了一种智能粮食湿度测试仪。
On the basis of research into the characteristics of grain's damp-resistivity and temperrature-resistivity, the digital signal processing unit which has the ability of automatic temprature compensation and of logarithmic amplification was designed and an intelligent humidiometer to test grain's damp was made in this paper.
