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;
nWhen 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;
nProducts 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;
nHigh-quality products using Songle relay can withstand 1500W load, to meet the requirements of most people;
nProducts with power indicator
nSupply voltage: 12VDC
nInput current: More than 100ma
nLoad: 250V 10A AC or 30V 10A DC (below current in this range can be used)
nSensor for detecting moisture in the soil;
nModule is the blue potentiometer to adjust the threshold for soil moisture , clockwise adjustment, control humidity will be bigger, smaller counter-clockwise;
nDue 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.
nProduct wiring information , refer to the picture below.
