Soil Moisture Sensor Corrosion Resistant

Ensure your plants always get the right amount of water with the Adafruit Soil Moisture Sensor. Unlike traditional resistive sensors, this sensor uses advanced capacitive sensing for accurate, long-term moisture detection without the risk of corrosion. Made from durable, corrosion-resistant material, it’s built to last, making it perfect for both indoor gardens and outdoor smart farming projects.

Simply insert it into the soil around your plants, and you’ll have real-time moisture data at your fingertips, impressing your friends with your smart gardening skills. This module features an on-board voltage regulator, supporting a wide operating range of 3.3V to 5.5V, making it ideal for low-voltage MCUs like Arduino, ESP8266, and ESP32. For Raspberry Pi users, just add an ADC converter for seamless integration.

Designed for plug-and-play simplicity, this sensor is compatible with Adafruit’s 3-pin "Gravity" interface, allowing it to connect directly to the Gravity I/O Expansion Shield for quick and easy setup. Whether you’re building an automated watering system, a smart greenhouse, or a data-driven agriculture project, this sensor is the perfect choice for precision moisture monitoring.
