The Water Leak Sensor 2 is our rope style water sensor. The rope/cord has an absorbent water-permeable braided jacket, that allows water to penetrate the jacket and complete an electrical circuit that is detected by the sensor. The sensor then reports the status change from normal to water-detected, which results in notifications being sent to you, activating a siren, turning off the water, etcetera, based on your predefined preferences in the app settings.

Rope type water sensors are ideal for detecting water in confined spaces, such as behind a refrigerator or under a dishwasher. They can also be used to detect water within a defined area or region, such as around a water heater or laundry machine, or within a large region, when additional cords are added. See the applications images for examples. 

Rope style water sensors are not ideal for water level monitoring. See our water level monitoring sensor selection for this application. Rope style water sensors are also not ideal for high-humidity environments. Consider one of our puck style water leak sensors for high-humidity environments.

The Water Leak Sensor 2 has an integral piezo sounder (mini siren). The sounder can be enabled or disabled in the app settings. Not using the sounder will maximize the life of the batteries. It is not recommended that the sounder on the sensor be the sole means of notifying you of a leak or flood. Please note: it is not recommended to rely solely on the sounder on a leak sensor, as you may be asleep and several floors and/or closed doors away from the sensor when it activates. Consider the Siren Alarm, the SpeakerHub  (e.g. on your nightstand), the Critical Alerts (severe weather style notification that activate audibly, even if the phone is in Focus or silent mode, available only to iOS phones), or app-specific notification settings that are loud enough to wake you, should be considered as primary methods to get your attention, even if you are asleep.   

This sensor should go upwards of 5 years between battery changes. Compare that to competitor products like those from Govee, that may need to be replaced as often as every 90 days!

Tip: the cable/rope can take an extended period to dry after getting wet. It is recommend to have a spare cable on hand, to replace the wet cable, after the leak or flood has been removed. Additional cables are available to purchase in the accessories section below.

The Leak Sensor 2 comes with a metal hangar, with 3M mounting tape pre-affixed, to hang it from a wall or other surface. See the optional ruggedized Wall-Mount Bracket for this sensor, which is ideal when the sensor is used at public locations, in apartments and rental properties, like condos and BNBs. The bracket, which can be screwed or adhered to the wall (screws included, other methods such as mounting tape, not included), affords the sensor additional protection against impact, casual tampering and cord removal.

The Water Leak Sensor 1 is our "puck" style water sensor. The Water Leak Sensor 1 is soon to be joined by the Water Leak Sensor 4 and 5, available July 2023. The Water Leak Sensor 1 is typically placed on the floor, where leaking or flooding water is expected. It has water-sensing electrodes on the top and bottom. The bottom electrodes are optimized for detecting flooding or pooling water, while the top, with its cupped region, is optimized for dripping water. 

A unique aspect of our puck style water sensors is that they are waterproof. It might be surprising to learn that many smart water leak sensors can be damaged by getting wet. The Water Leak Sensor 1 (and 3 and 4) will not need to be replaced if they get wet.

When a sufficient amount of water is on or under the sensor, water creates a closed electrical circuit between a pair of electrodes. The sensor then reports the status change from normal to water-detected, which results in notifications being sent to you, activating a siren, turning off the water, etcetera, based on your predefined preferences in the app settings.

Our selection of puck style water sensors are nearly universal water sensors; they can be used in almost any residential application. Spaces may be too small for a puck sensor, so you might consider the Water Leak Sensor 2, our rope style sensor. For air condensate pan or pipe overflow/back-up detection, consider our Water Leak Sensor 3 (our probe cable style leak sensor), or our Water Level Monitoring Sensor (with float switch).  The Water Leak Sensor 3 is also more ideal for laundry machine water drain pipe back-up/clog detection. See the below sections for more information on these sensors. 

Unlike the Water Leak Sensor 2, the 1 does not have a built-in piezo sounder (mini siren). The new puck style sensors, the Water Leak Sensor 4 and 5 do have integral sounders. Please note: it is not recommended to rely solely on the sounder on a leak sensor, as you may be asleep and several floors and/or closed doors away from the sensor when it activates. Consider one of our sirens, the SpeakerHub (e.g. on your nightstand), the Critical Alerts (severe weather style notification that activate audibly, even if the phone is in Focus or silent mode, available only to iOS phones), or app-specific notification settings that are loud enough to wake you, should be considered as primary methods to get your attention, even if you are asleep.

It is not recommended that the sounder on the sensor be the sole means of notifying you of a leak or flood. Since you may be asleep at the time, and the sensor may be on another floor, with several closed doors between you and it, it may be unlikely to awaken you. Recommended notification methods, include but are not limited to Critical Alert (iOS devices) and loud tones for push notifications on your smartphone, the SpeakerHubaudio, talking- and sound/tone-playing-hub, and the indoor Siren Alarm. 

This sensor should go upwards of 5 years between battery changes. Compare that to competitor products like those from Govee, that may need to be replaced as often as every 90 days!
