1.Using the soil sensor to 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 indicator and relay instructions.
- Supply voltage: 12VDC
- Input Current : more than 100ma
- Load: 250V 10A AC or 30V 10A DC ( below current in this range can be used)
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.
