Decent for the price
It works, but the traces corroded after a few months of direct exposure. Good for testing and prototypes.

Great for Arduino Projects
This sensor works perfectly with my Arduino Uno. The sensitivity adjustment is very responsive and easy to calibrate.

Good but needs coating
Works well for rain detection. I recommend adding a conformal coating for long term outdoor use to prevent corrosion.

Sensitive and Fast
Detects even light drizzle quickly. Integrated into my automatic window closer system successfully.
Q: Is this suitable for soil moisture?
A: It is designed for rainwater detection. For soil, we recommend a dedicated capacitive soil moisture sensor.
Q: Is the analog output linear?
A: The analog output varies based on moisture conductivity, but it is not strictly linear across all conditions.
Q: How do I adjust the sensitivity?
A: Use the blue potentiometer on the board. Turn clockwise to increase sensitivity.
Q: Can this module operate at 3.3V?
A: Yes, the module supports operating voltages between 3.3V and 5V DC.
Q: Can I use this with a Raspberry Pi?
A: Yes, but ensure you use the digital output or an ADC for the analog pin as Pi GPIOs are 3.3V logic.
