5-Pack DC 12V Relay Soil Moisture Sensor Module for Automatic Watering

Features:

• Equipped with high-quality soil sensors that detect moisture efficiently. The nickel-plated surface increases conductivity, expands the detection area, prevents rust when contacting soil, and extends product lifespan.
• Capable of controlling a wide range of soil moisture levels. Use the potentiometer to set a threshold, where the relay activates when humidity falls below the set value and deactivates when above.
• Includes a delay function of 3-5 seconds to prevent the relay from flickering in critical humidity states.
• Built with high-quality Songle relays that can handle up to a 1500W load, meeting the needs of most users.
• Features a power indicator for easy monitoring.

Specifications:

• Supply Voltage: 12VDC
• Input Current: More than 100mA
• Load Capacity: 250V 10A AC or 30V 10A DC (usable within this range)

How to Use:

• The sensor detects soil moisture levels, and adjustments can be made using the blue potentiometer.
• Turning the potentiometer clockwise increases the control humidity threshold, while counter-clockwise decreases it.
• Due to the module's delay function, expect a 5-8 second waiting period after adjustments to observe changes in the relay and green LED indicator.

Package Includes:

• 5 x Soil Moisture Sensor Control Module
• 10 x 20cm DuPont Line
