Gravity Analog Soil Moisture Sensor For Arduino Temperature Sensor and Controller Electronic Hobby Kit

Monitor your plants with this upgraded Soil Moisture Sensor, ideal for smart gardens, potted plants, greenhouses, and agriculture projects. Using two corrosion‑resistant probes, it measures soil resistance to accurately detect moisture levels, helping you automate watering or get timely reminders before plants dry out. This new version features an ENIG (Electroless Nickel Immersion Gold) finish, which protects the nickel layer from oxidation and ensures long‑term stability and durability. ENIG offers excellent surface flatness, superior corrosion resistance, and reliable performance compared to common HASL finishes, making it especially suitable for long‑term soil contact. Designed for rapid prototyping and education, the sensor includes a Gravity interface for simple plug‑and‑play connection—no soldering required when used with compatible shields. It works seamlessly with Arduino via an IO expansion shield and operates at 3.3V, enabling easy integration with Raspberry Pi, Intel Edison, Joule, Curie, and other 3.3V or 5V development boards. Use this soil moisture sensor to: - Track real‑time soil moisture in home or urban gardens - Build automatic irrigation and IOT agriculture systems - Protect indoor plants from over‑ or under‑watering - Teach or learn about environmental sensing and electronics Whether you are a hobbyist, educator, or IOT developer, this is a reliable, must‑have sensor for any smart gardening or precision agriculture project.
