Description

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. The sensor’s corrosion-resistant PCB design makes i
