SYSTEM AND METHOD OF SENSING SOIL MOISTURE

摘要

A system and method of sensing the amount of moisture in soil are disclosed. According to an embodiment, a soil moisture sensing system comprises a circuit unit and a sensor link electrically connected to the circuit unit. The sensor link includes a plurality of segments, each segment including an LC circuit in which a capacitor is connected with an inductor. The circuit unit is configured to provide an oscillating signal to a first LC circuit of the sensor link, sense a first coupled signal in a second LC circuit of the sensor link, and determine a soil moisture level on the basis of the first coupled signal.
