## Description

Water Leak Detector Sensor Alarm: Home Water Flooding Monitor Smart Sink Overflow Monitoring Adjustable Wet Moisture Alert Pipe Leakage Drip Detection Warning for Basement Floor (2 Sensor) - desertcart.com

Review: There is one thing......... - The unit is not flawless but let me rattle off the good first. The unit is fairly sensitive. The unit reacts and alarms not instantaneously, but quick enough. Its light weight and size makes placement easy peasy. It's loud. Loud enough you're gonna hear it unless you've got a really big house. Now the ehhhhhh. This is a simple unit...check before you buy. It does not connect to wifi, bluetooth, send you notifications, there is no app and other than blaring its tiny little lungs out......... if you don't hear it that's on you. It is what it is. The design of the unit has some limitations in its ability to sense water. But in its defense it will detect a serious leak that is liable to cause damage in fairly quick time. On the top of the unit is a small area with two small parallel metal strips in a recessed area. This is the drip sensor. You have to be fairly accurate where you place the unit for it to be effective in detecting a drip, especially a small one. With that said a serious drip will eventually trip the other sensors and about that....... There are 4 small metal sensors on the bottom of the unit roughly placed near the 4 corners. There are tiny little feet that hold the sensors ever so slightly off the bottom surrounded by a plastic channel that goes around the bottom near these sensors. This forces the water to at least enter and fill this channel before reaching the sensors. These clearances are so small that I can only assume it is designed this way so that the unit will not false alarm from things like condensation on a surface or moisture from a wet rag placed near the unit. But be advised a wet surface is not enough to trip the alarm on the unit. Any standing water WILL alarm the unit and it doesn't take much. With all this in mind I think the best course of action to take advantage of this unit, place a small container of any kind under any area you suspect of a drip and set the unit in that container. The same holds true for any water appliance you're trying to protect. Place the unit where escaping water will splash or pool. Understand that this all goes to earliest detection possible because that is where you can really limit damage. I really think this unit will get any leak but these measures will help you catch it as soon as possible.
Review: Great Product/Invention! - Brilliant product! Water heater/AC unit previously flooded my floor a few random times. Now this wonderful little device has saved me from a lot of stress. The slightest dampness will trigger the alarm. The alarm is loud enough to hear several rooms away. I have recommended this sensor to many of my neighbors. It is also very affordable.
