Abstract

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

a soil profile moisture sensor is designed based on the principle of high-frequency capacitance

which can automatically and continuously monitor the dynamic water content.The sensor mathematical calibration model is established by test

and sensor-related performance is tested.By comparing the actual value of the soil moisture with the sensor measurement value

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

which apparently reflects the moisture gradient.It is suitable for the measurement of soil moisture at different depth of soil profile and application of agroforestry production with low-cost and low power consumption.
