  • Brand new

  • Material: CCL

  • Color: Blue

  • Supply voltage: 12VDC Input Current: more than 100ma

  • Load: 250V 10A AC or 30V 10A DC ( below current in this range can be used)


  • The surface is nickel-plated and has a wide sensing area, which can improve the conductivity and prevent the problem of rust in contact with the soil.

  • The corresponding threshold is controlled by the potentiometer. When the humidity is lower than the set value, the relay is activated. When the value is higher than the set value, the relay is disconnected.

  • With delay function, delay 3-5 seconds, when the humidity is detected in the critical state, the relay will not flash, stroboscopic phenomenon.

  • Suitable for moisture detection of soil.

  • Automatically watering vegetable gardens, gardens, and control of soil moisture in family pots.

  • Fine workmanship and good performance.

  • Long service life.

Package included:

  • 1 x Soil Moisture Sensor Control Module

  • 2 x 20cm DuPont Line


  • The blue potentiometer in the module is used for the threshold adjustment of soil moisture. When it is adjusted clockwise, the humidity will be bigger and the counterclockwise will be smaller.

  • Because this module has a delay function, when adjusting the humidity value, it needs to wait for 5-8 seconds for each adjustment. Look at the change of the relay, and the green LED light also has corresponding changes until it meets the requirements.

  • Please allow 1-2cm errors due to manual measurement.

  • Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.
