Capacitive Soil Moisture Sensor

- These soil moisture sensor modules use capacitance rather than resistance to determine the water content of soil. This offers significant advantages over resistive measurement. These sensors have only one probe, no exposed metal to rust, and don’t harm your plants by introducing electricity into the soil. They output an analog signal that is proportional to how wet the soil is.
- Operating Voltage: 3.3 to 5.5V
- As the soil gets wetter, the output value decreases, and as it gets drier, the output value increases.
