Determination of moisture content in oil palm fruits using a five-port reflectometer
Yee, Lee Kim; Zulkifly, Abbas; Mohamad Ashry, Jusoh; You, Kok Yeow; Cheng, Ee Meng (MDPI Publishing, 2011-04-06)This paper presents the development of a PC-based microwave five-port reflectometer for the determination of moisture content in oil palm fruits. The reflectometer was designed to measure both the magnitude and phase of ... -
Precise moisture monitoring for various soil types using handheld microwave-sensor meter
You, Kok Yeow; Lee, Chia Yew; Then, Yi Lung; Chong, Sheau Huey Chen; You, Li Ling; Zulkifly, Abbas; Ee Meng, Cheng, Dr. (IEEE Conference Publications, 2013)A handheld microwave reflectometer-sensor system is developed to operate from 1.35 to 1.95 GHz and used to measure volumetric and gravimetric moisture content in various types of soils from 0% to 45%. A small monopole ... -
