Good but delicate
Functions well for detection but the exposed traces might corrode over time if left outdoors without protection.

Sensitivity Issues
Had to adjust the potentiometer quite a lot to get stable readings. Works okay for heavy rain.

Great for Arduino Projects
Works perfect with my Uno board. The sensitivity adjustment is very responsive and easy to set up.
5 FAQ
Q: Does it provide analog rain intensity data?
A: No, this module provides a digital switch output only. It indicates presence or absence of rain.
Q: How heavy does the rain need to be to trigger?
A: It detects water drops directly on the nickel coated lines. Sensitivity is adjustable via the potentiometer.
Q: Is this module compatible with 3.3V logic?
A: Yes, this sensor works with both 3.3V and 5V DC operating voltages.
Q: What are the pinout details?
A: The three pins are VCC (Power), GND (Ground), and DO (Digital Output).
Q: Can I leave this sensor outside permanently?
A: We recommend protecting the PCB from direct exposure to elements to prevent corrosion over time.
