Okay for short term
Works well initially but noticed some corrosion on the traces after a month of constant water contact.

Reliable Module
Used this for a rain detection system. Very responsive to moisture.
5 FAQ
Q: Can I leave this submerged permanently?
A: Not recommended. Prolonged submersion may cause corrosion on the exposed traces.
Q: Is 5V safe for this module?
A: Yes, the operating voltage range is 3.3V to 5V DC.
Q: Is the output analog or digital?
A: This specific module provides a digital switch output (HIGH/LOW).
Q: Can this measure exact water level height?
A: No, this is a threshold sensor. It detects presence at specific points, not continuous depth.
Q: Does it come with code examples?
A: We provide a link to basic Arduino sketches in the product documentation.
