3pcs DC 12V Relay Controller Soil Moisture Humidity Sensor Module Automatically Watering

Features 1 Using high quality soil sensors do detect soil moisture the surface of nickel plated has widened the induction area can improve conductivity prevent contact with the soil rust problems and prolong life 2 When two products can control a wide range of soil moisture the corresponding threshold by adjusting potentiometer control humidity is below the set value start relay while higher than the set value the relay is disconnected 3 Products with the delay function delay of 3 5 seconds when the humidity is detected in the critical state the relay will not blink flicker occurs 4 High quality products using Songle relay can withstand 1500W load to meet the requirements of most people 5 Products with power indicatorSpecifications Supply voltage 12VDCInput current More than 100maLoad 250V 10A AC or 30V 10A DC below current in this range can be used Module for use Sensor for detecting moisture in the soil Module is the blue potentiometer to adjust the threshold for soil moisture clockwise adjustment control humidity will be bigger smaller counter clockwise Due to the module with delay function in the regulation of humidity values adjusted once every 5 8 seconds to wait around to see if changes in the relay the green LED lights also have a corresponding change until transferred to meet the requirement Product wiring information refer to the picture below Package includes 3 x Soil moisture sensor control module6 x 20cm DuPont line
