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.
