Capacitive soil moisture refers to a method of measuring the amount of water in the soil using the principle of capacitance. In this method, a sensor is placed in the soil, and it measures the change in the soil's ability to store an electrical charge (its capacitance). The amount of water in the soil directly affects its capacitance, as water has a higher dielectric constant than dry soil.
