Good module, tricky calibration
Took some time to set the threshold right using the potentiometer but works well now. Good value for money.

Probe corrosion concern
Functionality is good but the probe shows some rust after heavy use in wet soil. Might need replacement later.

Perfect for my greenhouse
Works exactly as described. The relay clicks clearly when moisture is low and triggers my pump automatically.
Q: What is the return policy if it fails?
A: We offer a 30-day return policy for defective units. Please contact customer service for assistance.
Q: How do I adjust the moisture sensitivity?
A: Use a small screwdriver to turn the blue potentiometer on the board while monitoring the LED indicator.
Q: Can it handle a 12V water pump directly?
A: Yes, provided the pump current draw does not exceed the relay rating of 10A.
Q: Does this work with 5V Arduino logic?
A: The sensor module operates at 12V. You may need a level shifter or relay driver to interface with 5V logic boards.
Q: Is the electronic board waterproof?
A: No, only the probe is water-resistant. The PCB module should be kept in a dry enclosure.
