Good value sensor
Sensitive enough for most tasks. Had to adjust the potentiometer slightly to get the right trigger point.

Needs calibration
Works but requires some tuning to avoid false positives when humidity is high.
5 FAQ
Q: Does it measure exact water level height?
A: No, this is a digital switch sensor indicating presence or absence of water at a specific point.
Q: Can I use this with 3.3V logic?
A: Yes, the operating voltage range is 3.3V to 5V, making it compatible with 3.3V systems.
Q: Is this sensor fully waterproof?
A: The sensing traces are exposed for detection, so the module itself is not submersible. Only the traces should contact water.
Q: What connector type is used?
A: It features a standard 3-Pin PH2.0 interface for easy wiring.
Q: How do I adjust sensitivity?
A: There is a blue potentiometer on the board. Turn it clockwise or counter-clockwise to adjust.
