Microwave Based Moisture Content Detection System
This paper focusses on detecting the moisture content (%) of tree leaves (Eucalyptus, Tea) with the help of
Microwave technology. Traditional method involves calculating the weight of the sample before and after drying, and then
detecting the moisture percentage. In this process, microwaves are passed through leaf samples and the reflected signal is
analyzed. Generally, this technology uses frequency shift, phase shift and attenuation as the main parameters in moisture
content detection. In our project, we analyze the frequency shift of the reflected signal and use it as a main parameter to
detect the moisture content.
