Abstract
Methods for determining moisture content can be divided into two types: direct measurement and indirect measurement. Among indirect measurements, nuclear magnetic resonance, infrared radiation and radio waves are the most commonly used measurement methods. At microwave frequencies, moisture will be polarized and oscillate, and the transmitted microwaves will be scattered, projected, reflected, etc. Therefore, the moisture content of crops such as grain can be determined from measured parameters.
