Answer: 
Usually, humidity will not set off the Basement Watchdog Water Alarm. Both of the sensors need to be connected by at least 1/32" of water. If this much moisture were to build up, however, it would trip the alarm. Please contact us directly for more information at 800-991-0466 ext 3 for tech support M-F 9-5 CST.

Answer: 
It should not - there are two electrical contacts on the bottom, over an inch apart, and it requires liquid water to create a circuit between them to activate the alarm. However, if it sits on a floor that gets significant condensation, such as in a very damp basement, that might be enough to trigger it.

On the other hand, as inexpensive as these are, your time is probably worth enough you could just buy a second unit for less than the value of your time to modify it. Read Less

Answer: 
The unit has an attached sensor which allows you to mount the unit and have a remote, wired, sensor. For example you can place the sensor in the back of a cabinete under a sink and mount the unit where you can access it easily. There are no controls. Battery in, unit on. Water under the sensors, loud noise. No water, shuts off.

Battery-Operated Water Alarm is rated 4.7 out of 5 by 195.
Rated 4 out of 5 by from Excellent with one caveat You can't go wrong for the price. This little box does one thing and it does it very well. One warning, typical of products using 9v batteries: when the battery needs replacing, the connector can be very tight resulting in a broken connector when removing it to replace the battery. This renders the whole unit useless (not worth replacing it for the price of a new unit). The guy at my local Home Depot suggested I place some silicone grease on the connector before attaching the 9v battery. Won't know for a few years if this is a solution, but it sounds like a good idea.

I had a few water leaks under the sink that this device caught immediately. I own about ten of these alarms now. I've had some of them for a few years. They are great. Set it on the surface and you're done. The sensor is easy to test. Just touch the two metal contact buttons on the bottom with your fingers. Watch your ears. It stops as soon as you discontinue the test. Small; a little bigger than a pack of smokes and a lot better for you. With the included wire, they are flexible enough to monitor remote locations. I even used one to detect a leak inside the ceiling by sticking bare wire to the back of the drywall (ceiling below an upstairs bath and toilet). I ran the wire through a tiny hole in the drywall and connected it to the alarm. If or when there's enough water to complete the electrical circuit between the two wires, the alarm will sound. I did this in a garage below a bathroom. Obviously, you wouldn't do it inside your house (well, maybe in a closet). I'm planning on monitoring my crawl space plumbing with one. Put them next to the washer, under sinks. Put one next to the bathtub if one of the kids has a habit of carelessly letting water get past the shower curtain. One alarm will cure them of that.

Rated 5 out of 5 by from Simple but very effective watchdog It doesn't get any simpler than this little device. It's meant to warn you if there is any water present in areas that you don't want it. It's basically a battery powered, very loud alarm that is triggered when water connects the two metal contacts on the bottom. Water conducts electricity so it acts like a switch to turn on the alarm. When you lift the contacts out of the water it breaks the connection and the alarm stops. It has a long cord stored inside that pulls out of the bottom so that it can be mounted on the wall and the sensor can be placed on the floor. If you choose to stand it on the floor, place it were it won't get knocked over easily because it won't work in this position till the water is about an inch deep. You want the contacts to be at the lowest point so as soon as water appears it triggers the alarm. It would have been nice if there were stabilizers on the bottom that either flipped out or snapped onto the unit when it's used in the standing position. If you think you might need to add more stability to it and your handy, it would be an easy fix. I would suggest placing it somewhere were it won't be knocked over yet still visible so that you can check it easily and you should be just fine. If you have children and pets that's another story. It also would have been nice if it had a low battery warning like smoke detectors. This is something you will have to keep an eye on or it most definitely will not warn you with a dead battery.
