Notes About This Item: Tested one to verify it was working (it was). Look to be in great condition. It may (or may not) have had some very light usage but looks to be new
Notes from Amazon:
This water sensor features a loud 100dB alarm, which is loud enough to be heard when a leak is detected. A Mute Button is available to silence the alarm.
This wireless sensor is easy to use, with no wire or setup required. Its mini size allows it to be placed anywhere a water leak might occur.
With a compatible gateway device (not included), you can monitor water leaks from your mobile phone even when you are not at home.
The sensor is easy to install and can be used directly in the kitchen, bathroom, laundry room, washroom, and any other location subject to water leaks and flooding.
The water sensor alarm will beep and flash a red light when the battery is low. You can also press the button to test the battery level. If the probe is not dry after an hour, the sensor will sound the alarm again.
Once triggered, you can mute the alarm by pushing the silence button on the water leak sensor. The alarm can also be muted via the app or a base station if connected to a compatible system.
