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.

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 181.
Rated 4 out of 5 by from Great purchase for the price. Also, READ MY HELPFUL TIP! Cons: *design and quality of the plastic housing seem a bit lacking *if you're not at home or are far enough away that you can't hear it, it can't help you *no low-battery chirp like smoke detectors Pros: *inexpensive (buy a few to increase your chances of catching a problem early) *sensitive (dry fingers on the contacts will set it off) *simply set it on the floor or pull the sensor portion off and hang it down into a sump pit, etc. *the battery is not being used until water completes the circuit HERE IS A HELPFUL TIP: After purchasing two for my basement, I set each of them in a dry bowl, slowly filled the bowl to about a half inch water depth and was disappointed that neither one sounded until I lifted each one out of the water. After drying them and drying the bowl, I tried a few more times with identical results. I believe an air pocket may be forming below the unit, preventing one or both of the contacts from touching the water. Here's the elegant, reliable, simple solution I came up with: place the unit on a piece of paper towel! This will help wick the water under the unit, ensuring water reaches both contacts. Repeating this test a few times with dry paper towels yielded repeatable results!

Rated 5 out of 5 by from This thing works! I'm sorry to report this thing works! Sorry, because we found out when it started squealing from the basement. Thought it was the smoke detector but quickly realized it was the alarm, alerting us that the main drain was backing up. It alerted almost instantly, allowed me to shut off the washer before it flooded stuff, and get the drain fixed before the backup caused real damage. Best $10 or so we've spent. I've added one under the kitchen sink, and behind the washing machine, as the other two most likely places to have a damaging leak and not know until it's too late. And installation consists of popping a battery into it, and setting it where the leaking water will puddle. Done. It'll take you longer to open the packaging than to set it in place.

Rated 5 out of 5 by from MUST HAVE This device just saved my wife and I thousands on potential flooding damage in our basement, we were notified in the middle of the night with plenty of time to react to water seeping in our basement from unusually high and fast amounts of rain. I will be buying another one for extra security as this product gets a 10 out 10 in my book

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.

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.

Rated 5 out of 5 by from Solution to a horrible problem The product seems well designed and when tested worked as advertised. It took very little water to cause the alarm to sound and all I had to do was wipe the contacts to shut it off. I have two by the basement door, which is at the end of an outdoor concrete staircase. We have had three floods (about 1/8 inch of water) recently and I took several precautions against repetitions which seem to have worked. The alarms are a backup should we have water again. Of course if the alarms sound we have to be home to get the vacuum going so if you are frequently away, work or travel, they will be useless. Then I would suggest a more sophisticated system with remote monitoring. Even so you still need to attend to the water. I bought a third one and placed it near the washing machine. Quite frankly, the best solution is to sell the house and find a dry one.

Rated 5 out of 5 by from Battery operated WATER ALARM The battery operated WATER ALARM is easy to install, just install batteries and mount the alarm box to the wall. The alarm is loud, you can easily hear it from your basement to your first floor. The sensor has a 6 FT cable and the length can be increased if needed by adding additional cable. I located my alarm in my mechanical room between the Hot Water tank and the Boiler.
