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

from 1634 reviewsI 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.

The switch increased my lighting option. Installation easier with stranded wire.
Have 2 in my garage freezers and they work. I like the secure feeling knowing we are protected.
Smart Wireless Thermometer, Wide Temp Range for Freezer, Fridge, Green House, Pet Cage, App Alerts, Emails, Text/SMS alerts- Hub Required
Flowsmart meter/leak detector works great on my irrigation line at meter 400 feet from my home. No more costly undetected leaks.
We have a mail box rather far from the house. it has been a hassle checking for mail before it was delivered. Now I just check the app instead of going to the mail box. The range is increadible. I was a bit tricky to install it since the adhesive is for side by side positioning and here the door is perpendicular to the side of the mail box but after tinkering with it a bit I figured out how to mount it so that it works perfect. VERY VERY happy
Temperature & Humidity Sensor, Hub Required!
it took maybe 10 minutes to install including downloading and installing the app. I got the speaker hub which is nice because it announces when the garage door is opened and closed. The connection is great from the third floor to the ground floor on the other side of the apartment building.
I use the Smart Motorized Valve to control my outdoor water use with Home Assistant. When my rainwater cisterns are full, the valve closes and forces the irrigation to use collected rainwater. When the rainwater cisterns are depleted the valve opens and lets the irrigation use town water.
