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 1647 reviewsThe set up was very easy however getting the sensors to react was a little tricky. I had to contact customer support to get the right instructions. They did send me step by step instructions so it all went well. Hopefully, the system will never be used but I have tested it and the sensors to make sure that should a leak occur, it will be handled correctly and automatically, just as I want it to. Good thing I did do a test because there was an item near the controller that was impeding the arm closing all the way. Had I not, I would have had an issue. Just a word of advice. Once you set it all up, test your sensors to make sure that the power pack reacts the way you need it to. The snesors are very sensitive so that is a big plus. A wet napkin will set them off.Highly recommend this system.
Itās exactly what I needed! I have the speaker set to say a warning phrase if someone enters our horse barn between certain hours in the night and early morning.
Works great. Well worth the price.
I am using my siren with the six outdoor motion sensors that I placed around my house. The siren works great. The setup was easy.
I purchased the YoLink Door Sensor Starter Kit with a YoLink Hub. I love this initial set. I use it on a condo that I rent. I can easily monitor when the renters arrive and if they have the door open and the AC turned on. Great money saver. Works great and all the time.
GREAT PRODUCT!!!
I ordered four more relays.
Ordered for Amazon, they were a $1.00 less on each and shipping was free.
When I need addition modules, will YoLink have free shipping.
YoLink Hub with Two Temperature & Humidity Sensors, Smart Home Starter Kit
Got it all set up in minutes. Tested great. Easy to use. Huge leak detection footprint with the cord. Integrates with Home Assistant. Long battery life, long distance wireless. Didn't like having to set up a whole new hub for my smart home, but that's a minor inconvenience.
I now own 8 temp/humidity units and 2 hubs. This system is easy to setup and work great.
I went on a walk. I was at least 1/4 mile away and tested my plug on a light it worked I was amazed.. real game changing tech.. Thank you Yolink for a great product! PS I also really like how you included a charging port for the fob!
The product works without any issues. Instructions were good. Door notifications , open & closed are punctual. Thanks great value.i also have room & refrigerator/ freezer modules on system. Power went down and I was notified of temperature problem . That paid for the equipment. Thanks so much , I am very happy I bought it .
Works like a dream perfect solution for what I need
So our farm building are spread out a bit. Greenhouse, special raking systems inside greenhouse, storage rooms, open fields, pump house at the far end. And ai always know what the temperatures are. Sometimes it causes me to get up, put on a robe and head outside at midnight. And that is a good thing. Oh, and the original set of sensors has been up a couple of years.
