Water sensor using DS10A

[BraveSirRobbin]

Well, remember the DS10a will detect a 'transition' from high resistance to low resistance. If the board never gets to the 'high' resistance state (i.e. dry) the DS10a will never see the transition when wet again.

Thanks BSR. The way I normally test these is to drop a few drops of water on them. Then use a hair drier to dry them off to reset them. I'm retesting all my sensors again. I took some alchol and cleaned the sensors just in case. I'm beginning to wonder if something was on the sensor under the sink and it was already in a alert state. My logic didn't indicate that but I'm reworking that as well. Thanks for all the help and I'll let you know what I find.

Maybe I should try this with a NX-650 sensor....

a couple more water sensors that may be hacked to a ds10a:
