How It Works

The sensor probe is inserted into the soil, where it measures electrical conductivity between its conductive traces. As soil moisture increases, conductivity rises, resulting in a change in the sensor's output signal. The control module processes this signal and provides both analog and digital outputs, enabling users to monitor moisture levels or trigger automated actions such as activating water pumps and irrigation valves.
