Abstract :
In order to obtain accurate calibration model of TDR-based sensors for monitoring soil water content, TDR-based sensor was calibrated using Takagi-Sugeno fuzzy model. The precision of calibration model was verified by correlation coefficient. The experimental results show that the calibration model based on the Tagagi-Sugeno fuzzy model gets high accuracy of piecewise linear fitting. Wireless Sensor Networks in measurement of soil water content is access to more accurate values of soil water content using the calibration model, so that real-time monitoring of soil water content make key progress.
