Research and Design of a FPGA-based SWR Soil Moisture Measurement Instrument
Jian Sun · Anhui nongye kexue · 2012
Based on the principles of measuring soil moisture content by means of standing wave,a FPGA-based new measuring instrument was proposed.The instrument has modules like measurement control,AD control,data processing,display control,high frequency signal controller,etc.,all of which are integrated in a FPGA chip.The instrument has advantages of low cost,compact structure,strong anti-interference capacity and quick measurement,etc..
