传感器的最大绝对测量误差为-5.10%;传感器用于土壤剖面不同深度的土壤水分测量

水分梯度变化明显

性能良好。

Abstract

In order to achieve soil moisture measurement of different depths of soil profile

a soil profile moisture sensor is designed

especially circuit of sensor node is designed and implemented which is low-cost and low power consumption.The experimental results show that the sensor output voltage with this circuit decreases with soil moisture content increasing

and by comparing the actual value of the soil moisture with the sensor measurements

the maximum absolute error of sensor is-5.10 %.The sensor can be used for measurement of soil moisture at different depth of soil profile

moisture gradient change is apparent

the performance is good.
