Corrodes over time
Works well initially but the exposed traces started to corrode after a few months of constant outdoor exposure. Might need conformal coating.

Great for Arduino projects
Works exactly as described. I used this for a simple rain alarm system and the sensitivity is adjustable via the potentiometer. Very easy to integrate.

Good sensitivity
Easy to use but requires some calibration to get the threshold right for light rain. Overall good value for the price.

Perfect for leak detection
Set this up under my sink connected to a smart home hub. It triggers instantly when water touches the pads. Peace of mind.

Fast delivery
Module arrived quickly and was well packaged. Tested it with a 5V relay and it switches perfectly when wet.
Q: Can I use this with 3.3V logic boards?
A: Yes, the module operates comfortably between 3.3V and 5V DC, making it compatible with most microcontrollers.
Q: Can it measure specific water level depth?
A: No, this is a presence sensor. It detects if water is bridging the traces on the board, not the depth of the water.
Q: Does it come with connecting wires?
A: Yes, the package includes one 3-pin Dupont cable to connect the module to your controller.
Q: Is this sensor analog or digital?
A: This module provides a digital output (HIGH/LOW). There is a potentiometer on the board to adjust the sensitivity threshold.
Q: How long can it stay submerged in water?
A: It is designed for detection purposes. Prolonged submersion may lead to electrolysis and corrosion of the nickel-plated lines over time.
