Smart Water Depth Sensor
The water depth sensor measures the depth of water in a tank or container, and its compact design and wired probe allows for placing the sensor where others may not fit. Ideal for water tanks, aquariums, pools, ponds, and more.
Lower cost of ownership than other technologies; low-power operation means batteries may last up to 10 years. Carefree maintenance, and low-battery alerts give you advanced warning that it is almost time to replace the battery.

LoRa Range Water Depth Indicator
YoLinkās industry-leading long range communication (up to 1/4 mile, open air) allows for operation in larger homes and in areas difficult for other wireless systems, such as basements, separate garages/structures, and even outside your home.
Through the app, be informed immediately of low, or high, water levels wherever you are and set up levels to receive email, SMS/text, and banner notifications on your smartphone. Create custom automation using the app, to trigger responses from other YoLink devices, such as the Siren Alarm. Additionally, view exportable historical data chart and logs of water depth.

Water Depth Detector Applications
Water level detection applications include monitoring water levels in water supplies, such as those used for livestock, plants, gardening, horticulture, and agriculture

Let customers speak for us
from 1369 reviewsSet up is pretty great in terms of ease & quickness. It was confusing to figure out how to get sensors to actually talk to the siren alarm but the agent - Genevieve - was very helpful in walking me thru those 14 steps. Maybe I missed it but it would great to have a visual guide that gives easy instructions on that part.
Thanx so much!

Using it to lock and unlock doors at the office. Works just like it says and was easy to setup and get working.

I have not installed yet but when I do I will send a review

Really gives you peace of mind to know that all fridges and freezers are working in my house and also have the water sensor in all risk areas which is nice

Very pleased with how the sensor works. Even more pleased with your customer service - I can always reach a live person who capably answers my questions.

I have purchased a couple dozen YoLink Water Sensor 2 and Water Sensor 4 units. They all connected to the hub and app immediately, first time, with zero issues. They all work perfectly and they easily connected to a YoLink automated water valve with device-to-device (D2D) pairing. This allows a leak detector to shut off the main water valve with no internet and no hub connection. I've had zero false alarms from the couple dozen sensors I have deployed across 2 homes. I absolutely will buy more YoLink products.

Motion Sensor 3-Pack, YoLink Hub Required!

These things are great. Cover a nice area with the optional 10' extension. Wish I would have bought more of these originally instead of the leak 1 sensors.

Simply great execution. Upgraded from a Honeywell ProSeries that lacked connectivity. Easy wire switch and an incredibly intuitive app made for an easy transition. Now I can turn the heat up just before my arrival even with dynamic travel plans. A great efficiency booster!

Searched everywhere for a solution to the random water pipe leaks costing thousands of dollars in our apartment complex. When coupled with the bulldog valve and detectors, they fit the bill for saving us from large destructive flood events. The speaker hub being able to tell you where the leak is saves searching so you can get straight to the problem. Great pro

Temperature & Humidity Sensor 3-Pack, Hub Required!

Works just like the website and video says it works. no problem:)

Our block of units has been plagued with water leaks for a few years now and this system will hopefully detect leaks before they become floods. We are on our third rebuild after leaks both from our own unit and those above. I showed the system to other owners and they decided we would all fit them to our units given the history and costs of repairs. Insurance may even reduce if we present our case. Highly recommended.
