本文设计并制作了一种可以实时在线监测土壤电导率的无线传感器系统，传感器可以长期埋藏于被监测区域的土壤中，监测土壤的电导率，反映土壤中含水量和可溶盐的多少，能够广泛的应用于农业生产、文物保护、环境监测等领域。实验结果，该装置能够在户外的应用环境下长期稳定的工作，具有精度高、响应快、功耗低、无线数字收发、不扰动原有土壤等优点。%In this paper,a wireless sensorsystem was designed and made,which can monitor oil electrical conductivity in the way that real-time and on line.Sensorwasburied in the monitoring regionof the soil,monitors soil electrical conductivity and reflects the trends of soluble salt and moisture content.This system can be widelyapplied in the field ofagricultural production,the protection of cultural relics,environmental monitoring and so on.The experimental results thatthis system we designed can be used in theapplication environment ofout door long-term and stability. This system has the advantages of high precision,fast response,low power consumption,wireless digital transceiver and undisturbedoriginalsoiletc.
