Perfect for my rain alarm
Works great with Arduino Uno. Very sensitive to water droplets. Easy to integrate into my weather station project.

Corrodes eventually
Worked for months but the traces started corroding after continuous exposure to tap water. Good for temporary use.

5 FAQ
Q: Does it give depth measurement?
A: It detects presence or level based on contact. It does not measure exact depth in centimeters.
Q: How long do the traces last?
A: Depending on water quality and exposure time. Continuous submersion may reduce lifespan.
Q: Is this fully waterproof?
A: The sensor lines are exposed for detection. The PCB itself is not waterproof for submersion.
Q: Can I use this with 3.3V logic?
A: Yes, it supports 3.3V to 5V DC operating voltage range.
Q: What connector type is used?
A: It uses a standard 3-pin PH2.0 connector for easy wiring.
