Product Description

Capacitive Soil Moisture Sensor Module

= Corrosion-Resistant Analog Sensor for Arduino and Plant Monitoring =

This Capacitive Soil Moisture Sensor module is a durable and reliable electronic device designed to measure the volumetric water content in soil . Unlike traditional resistive sensors, it uses capacitive sensing technology to detect moisture levels by measuring changes in the soil's dielectric constant, which is directly affected by water content . This design is highly resistant to corrosion, ensuring a long service life for garden, agriculture, and smart irrigation projects .

CorrosionResistant Design Capacitive sensing extends the sensor's lifespan compared to resistive alternatives.
Wide Voltage Operation Includes an onboard regulator for 3.3V to 5.5V compatibility .
The sensor provides an analog voltage output that correlates to moisture levels. Typically, higher moisture results in a lower output voltage .
