Model and Algorithm for Wood Moisture Content Detection by Capacitance Sensor

Abstract:

In this article, a model which was used to measure wood moisture content(MC) was presented. It was founded under non-uniform and asymmetric conditions and there was no any need for wood shape. It can work out the relationship between capacitance value( ) and dielectric constant( ). Compared with previous methods, it not only can greatly lessened measuring work, but also avoided the waste of media resources, such as wood. At the same time, a new kind of numerical method was given for this problem. The number of unknown variables significantly are reduced by doing this.
