Capacitive Analog Soil Moisture Sensor – 3.3–5.5V Output

The Capacitive Analog Soil Moisture Sensor is designed to measure soil moisture levels for automated irrigation and plant monitoring systems. It operates by detecting changes in capacitance caused by water content in the soil, eliminating corrosion issues common in resistive sensors. The sensor provides a stable analog voltage output and operates from 3.3 to 5.5 V, making it compatible with both 3.3 V and 5 V microcontrollers. An onboard voltage regulator ensures reliable performance across the full supply range. It is suitable for home gardening, educational projects, and smart agriculture prototypes.
