    Humidity is lower than the set humidity start referring to is when soil moisture is lower than setting humidity, the relay will automatically pull in, start the spray, water pumps, etc. do humidifying movement, reaches the desired humidity automatically stop.






    Product use:


    Through the potentiometer adjusting soil moisture threshold control, automatic in garden, garden automatic watering, family flowerpot soil humidity control, all kinds of electronic games, with high power relay, can control large current device, less than setting humidity automatic start relay, greater than setting humidity automatically disconnect and delay function, without delay of critical humidity state relay don't stop flicker problem solving is a simple and practical soil humidity control system.




    Product introduction:


    1. Using the company's production of high-quality soil sensor for detection of soil moisture, and the surface of the nickel plating, widening of the sensing area can improve conductive properties, prevent soil contact is easy to rust, prolong service life;


    2. The product can be a wide range of control soil humidity and control the corresponding threshold value by adjusting the potentiometer and the humidity is lower than set value, start relay, is higher than the set value, the relay is switched off.


    3. Product with the function of time delay, delay 3-5 seconds when detected humidity in the critical state, relay will not blink, stroboscopic phenomenon;


    4 products using high quality relay, can withstand the load of 1500W, to meet the requirements of most people;


    5 products with power indicator and indicator relay;




    Electrical parameters:


    Supply voltage: 12VDC input current: more than 100mA


    Load: 10A 250V AC or 10A 30V DC (lower than the current in this range can be used)




    Module instruction:


    1 sensors applied to the detection of soil moisture;


    Module 2. Blue potentiometer is used to soil moisture threshold adjustment, clockwise adjustment and control the humidity will be bigger, counterclockwise smaller;


    3 due to the module with delay function, adjust the humidity value, once every tune need to wait about 5-8 seconds, see the change of the relay, the green LED lamp also has the corresponding change, until adjusted to meet the requirements.
