8 Pcs 12V Soil Moisture Sensor Relay Control Module for Automatic Watering, Humidity Activated Switch

Features: 1. Soil sensor module for moisture detection. Surface plating improves conductivity and reduces corrosion risks during soil contact. 2. Adjustable potentiometer allows for controlling soil humidity thresholds. Relay activates when humidity is below the set value and deactivates when above. 3. Includes a 3-5 second time delay function to prevent relay blinking during critical humidity states. 4. Equipped with a relay capable of handling loads up to 1500W. 5. Contains power and relay status indicators. Electrical Parameters: Supply Voltage: 12V Input Current: More than 100mA Load: 10A 250V AC or 10A 30V Module Instruction: Sensors are used to detect soil moisture. The blue potentiometer adjusts the moisture threshold; rotate clockwise to increase the set humidity and counter-clockwise to decrease. Due to the delay function, wait approximately 5-8 seconds after adjustment to observe relay and green LED lamp changes. When soil moisture is lower than the set humidity, the relay pulls in to start water pumps or sprayers. Operation stops automatically when desired humidity is reached.
