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.
