Capacitive Soil Moisture Sensor Module

The Capacitive Soil Moisture Sensor Module is a high-quality, durable sensor designed to measure the moisture content of soil using capacitive sensing technology. Unlike traditional resistive soil sensors, this module does not corrode over time, making it highly reliable and long-lasting for real-world applications like smart farming, gardening automation, and IoT-based agriculture systems.

The sensor detects soil moisture levels by measuring changes in capacitance, which vary with the water content in the soil. It provides an analog voltage output that can be read by microcontrollers such as Arduino, ESP32, Raspberry Pi, and others to determine moisture levels in real time.

Whether you're building a smart irrigation system or simply monitoring plant health, this sensor is ideal for indoor and outdoor use due to its waterproof PCB coating and robust design.
