Review on Sensor Module Detection Surface Arduino（10Pcs） by Johnny Bloomer
Doesn't work - signal is LOW by default
So my goal was to make a simple leak detector with it, so I didn't worry about the level, just the presence of water. However, when I connect them to my Arduino, by default it outputs a LOW signal with no water. So I checked the back to see if this version differs from the others, but the signal doesn't change whether they're in the water or on land. I'm using a saltwater mix so I'm sure I have a wired connection, but the fact that I'm getting a weak signal from the start leads me to believe they're buggy. Of course when I ordered them I had other projects and so my 30 days have just expired so I can't return them.
