基于TDR的土壤水分传感器设计与试验
Design and Experimental Research of an Instrument for Soil Moisture Sensor Based on TDR
摘要
Abstract
For the actual need for observing the environment required for the growth of crops under farmland soil moisture regime ,developed a new type of soil moisture sensor based on the principle of TDR .Equivalent sampling theory and using incentives to build high-speed narrow pulse waveform reconstruction method , and PC software design and development of PC, using Bluetooth technology TDR measurement equipment and PC software to communicate real -time wireless trans-mission of measurement results .To test its performance , conducted four different calibration test soil texture , and Easy Test with Poland's FOM /mts type TDR for comparison .The test results showed that the soil moisture sensor in a non-saturated state , the measurement results with actual soil moisture linear correlation reaches 0.97 or more, and almost free from influence of soil texture , has a certain application value .关键词
