DFRobot Gravity: IP65 Capacitive Soil Moisture Sensor for Arduino / ESP32 / Raspberry Pi

The Gravity Capacitive Soil Moisture Sensor offers IP65 waterproof protection and corrosion resistance, designed for long-term outdoor gardening, automated irrigation systems, and environmental science projects. Using advanced capacitive sensing technology, it outperforms traditional resistive sensors with higher accuracy and durability in humid or wet soil. This sensor provides an analog output signal, making it easily compatible with popular microcontrollers like Arduino, ESP32, and even Raspberry Pi (with an external ADC module), ensuring reliable moisture monitoring for optimal plant health in harsh outdoor conditions like balconies, gardens, and farms.

Fully Waterproof Design

The entire body of the sensor is waterproof, allowing it to be fully submerged in water without any performance degradation. This ensures reliable operation in outdoor gardens, greenhouses, and potted plants where exposure to water and humidity is frequent. Whether used in heavy rain or constant irrigation, the sensor continues to deliver accurate readings.

Corrosion-Resistant and Durable

Designed with longevity in mind, the sensor's capacitive measurement principle eliminates the corrosion risks common in traditional resistive sensors. The robust construction prevents the sensor from wearing down even when left in soil for extended periods, reducing the need for frequent replacements. Its scratch-resistant surface further enhances durability, making it perfect for long-term use in harsh environments.
