3-Pack DC 12V Soil Moisture Sensor Module with Relay Controller for Automatic Watering

Product Features

• Equipped with high-quality soil sensors that effectively detect soil moisture. The sensors feature nickel-plated surfaces to enhance conductivity, prevent rust, and extend lifespan.
• Adjustable soil moisture control: Two units can manage a wide range of soil moisture levels. Use the potentiometer to set the threshold; the relay activates when moisture falls below the set value and deactivates when it rises above it.
• Incorporates a delay function to prevent flickering: The relay delay of 3-5 seconds ensures stability when moisture is at critical levels.
• High-quality Songle relay: Capable of handling a 1500W load, suitable for most applications.
• Includes a power indicator for easy monitoring.

Specifications

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

Module Usage

The sensor is designed to detect moisture levels in the soil. Adjust the blue potentiometer to set the desired soil moisture threshold: turning clockwise increases humidity control, counter-clockwise decreases it. The module's delay function requires a 5-8 second pause for relay changes, indicated by a green LED, ensuring optimal settings.
