| Abstract: | Wireless sensor networks composed of TDR soil moisture sensors for real-time monitoring variation of soil water content. In order to improve accuracy of the calibration of the TDR soil moisture sensors, the Takagi-Sugeno fuzzy model was proposed for calibrating the sensors. The precision of the calibration model was verified through correlation coefficient. Results show that the calibration model based on the Tagagi-Sugeno fuzzy model realized simple piecewise linear fitting and improved accuracy of the sensors. |
