DC12V Soil Moisture Sensor Relay Control Module Automatic Wa

Features:

• 
  This module can control humidity of soil in a wide range and set control threshold by adjusting potentiometer. When humidity is lower than the set value, relay is energized;  when humidity is higher than the set value, relay is dis-energized.
  
  
• 
  High quality soil moisture sensor has nickel plating surface, widened induction area, can improve conductive performance and prevent rust problem when contact with the soil to prolong service life.
  
  
• 
  It has time delay function, delay 3-5 seconds, when humidity is detected in the threshold state, the relay will not flicker.
  
  
• 
  Adjusting soil moisture control threshold by potentiometer (clockwise to increase, counterclockwise to reduce), it can control soil humidity and automatically watering vegetable garden, flower garden or pot.  
  
  
• 
  Because this module has time delay function, when  adjusting humidity, you need to wait for 5 to 8 seconds to check the change of relay, and the green LED lights will change, until it is adjusted as required.
