Soil Moisture Sensor Module – Analog and Digital Output

The Soil Moisture Sensor Module is designed to measure moisture levels in soil and similar materials using conductivity-based sensing. It features dual analog and digital outputs for flexible integration with microcontrollers. The exposed probe pads act as a variable resistor, where increased soil moisture improves conductivity and raises output levels. Operating at 3.3–5 V, the module ensures stable and reliable performance across different platforms. It is suitable for irrigation control, environmental monitoring, and educational electronics projects.
