Detail Description

🔹 Product Description (EN)

A Soil Moisture Sensor Module is an electronic device used to measure the moisture level (volumetric water content) in soil. It is widely used in automated irrigation systems, smart gardening, and agricultural monitoring to help determine when plants need watering.

By monitoring soil moisture in real time, this sensor helps prevent overwatering and underwatering, improving plant health and water efficiency. It can be easily interfaced with microcontrollers such as Arduino, ESP, and other development boards.

🔹 Types of Soil Moisture Sensors

1️⃣ Resistive Soil Moisture Sensor

Description:

Measures soil moisture by detecting the electrical resistance between two probes inserted into the soil. Higher moisture reduces resistance, while dry soil increases resistance.

Advantages:

Simple working principle
Low cost
Easy to use

Disadvantages:

Prone to corrosion over time
Accuracy may degrade with long-term use

2️⃣ Capacitive Soil Moisture Sensor

Description:

Measures soil moisture by detecting changes in the soil’s dielectric constant, which varies with moisture content. It does not rely on direct electrical contact between exposed probes.

Advantages:

More durable and long-lasting
Resistant to corrosion
More stable and accurate readings

Disadvantages:

Slightly higher cost compared to resistive sensors

🔹 Applications

Automatic irrigation systems
Smart gardening projects
Agricultural soil monitoring
IoT-based farming solutions
Plant care and research

⚠️ Warning & Usage Notice

Avoid immersing the electronic module in water.
Use proper voltage levels as specified.
Clean the sensor after use to extend lifespan (for resistive type).
Not suitable for extreme environmental conditions without protection.
