Reliable detection

I used this for a rain alert system. It triggers consistently when water bridges the gaps. Very satisfied with the build quality.

Does the job

Simple and effective. Wish the cables were a bit longer, but I extended them myself. Detection is instant.

Good value but sensitive to corrosion

Functionality is great for the price. Just note that leaving it submerged constantly may cause corrosion on the traces over months.

Perfect for my aquarium auto-fill

Works exactly as described. Easy to interface with my Arduino Uno. The sensitivity is adjustable via the potentiometer.
