Capacitive Soil Moisture Sensor Analog Soil Humidity Sensor

The Capacitive Soil Moisture Sensor is a high-quality sensor designed to measure soil moisture levels without corrosion or degradation. Unlike traditional resistive sensors, this module uses capacitive sensing technology, which detects the water content in soil based on changes in dielectric permittivity — ensuring longer lifespan, higher accuracy, and reliable performance. It is ideal for Arduino, ESP32, Raspberry Pi, and other microcontroller-based smart garden and irrigation projects. The sensor outputs an analog voltage that varies with soil moisture, allowing users to monitor real-time soil conditions and automate watering systems.
