Great for automation projects
Integrated this with my smart home system. The 12V option is very convenient for driving larger loads via the relay. Highly recommended.

Perfect for my greenhouse automation
Works exactly as described. I connected it to my Arduino to close the roof windows when it starts raining. The sensitivity is great and the relay clicks firmly.

Sensitive but robust
Good detection area and it survived a heavy storm last week. Only reason for 4 stars is the cable could be a bit longer for my setup.

Survived the monsoon
Left it outside for weeks under partial cover. No corrosion on the contacts and it still triggers reliably when water hits the surface.

Relay is loud
Functionality is good and it detects rain well. However, the mechanical relay makes a loud clicking sound which might be annoying in quiet environments.
Q: Can I use this sensor with 3.3V logic microcontrollers?
A: Yes, but you may need a logic level converter since the module operates at 5V or 12V. The output signal matches the input voltage.
Q: Does this come with mounting screws?
A: No, mounting hardware is not included. The holes are standard 4mm diameter to fit common M3 or M4 screws.
Q: Is the sensitivity adjustable via a potentiometer?
A: No, this model has a fixed threshold designed for reliable rain detection without false positives from humidity.
Q: What is the warranty period for this module?
A: We offer a 12-month manufacturer warranty against defects in materials and workmanship.
Q: Can it control a water pump directly?
A: Yes, via the onboard relay. Ensure the pump current does not exceed 10A to avoid damaging the relay contacts.
