heal.abstract	In this paper, the conversion of a PC or laptop-controlled microwave moisture meter to a stand-alone meter hosting its own embedded system is discussed. The moisture meter uses low-power microwaves to measure the attenuation and phase shift of the sample, from which the dielectric properties are calculated. The dielectric properties are then used to determine instantaneously and nondestructively the moisture content in the grain or seed sample. The previous system consisted of the moisture meter being controlled via USB interface by an external laptop or PC. Though effective, the system lacked full portability and was susceptible to laptop crashes and interruptions in communication between the meter and laptop. To improve the system, a microcontroller was selected in the design of an embedded system for the moisture meter. The microcontroller provides a graphical 144 x 32 pixel LCD and 16-button keypad to facilitate user interaction. The embedded system provides the following functionalities: user interface (input/output), event execution, process control, data acquisition, and data storage. Initial testing shows that the moisture meter with the new embedded system maintains the performance and accuracy observed in the original PC or laptop controlled meter. The integration of the embedded system with the microwave moisture meter provides a cost-effective, portable, and robust solution for microwave moisture sensing.	en
