Gravity: Analog Capacitive Corrosion Resistant Soil Moisture Sensor for Arduino / Raspberry Pi

The Gravity Analog Capacitive Soil Moisture Sensor is a durable environmental sensing probe designed for use with microcontrollers such as Arduino and Raspberry Pi. It provides real-time soil moisture tracking without the rapid degradation common in standard resistive alternatives. This sensor is ideal for students, hobbyists, and makers building automated irrigation or smart agriculture projects.

Capacitive sensing technology

The sensor measures soil moisture levels capacitively rather than passing an electrical current directly through the soil. This prevents contact corrosion and maintains reliable measurement accuracy over time.

Extended operational lifespan

Designed for continuous soil deployment, this unit offers two to three times the operating lifespan of conventional resistive soil probes. It is built to endure extended monitoring cycles in moist environments.

Waterproof detection area

The sensor features a waterproof detection area tailored for safe insertion into wet soil. This ensures the sensing components operate reliably when buried in damp substrates.

Targeted plant and garden monitoring

The probe excels at monitoring moisture levels in potted plants, flower beds, and indoor gardens. It delivers clear analog feedback to help prevent under-watering or over-watering in automated setups.
