Each sensor has a 105 dB alarm when enabled. Get app, email and SMS alerts through a powered, online YoLink hub (SMS limits apply). Name sensors by room to know where to check. - LoRa coverage up to 2034 feet: Low-power LoRa radio connects sensors to the hub across large properties, helping you monitor basements, laundry rooms and other indoor leak-prone areas. Up to 2034 feet (620 meters) in open air; walls, metal and placement affect actual range. - Add automatic shutoff, even during outages: Control-D2D lets a sensor directly trigger multiple compatible YoLink shutoff devices, including EVO, Bulldog, motorized valves and FlowSmart ultrasonic meter/shutoff systems. Once paired, local control works without internet or hub power while sensors and shutoff devices remain powered and in range. Choose battery-powered shutoff options for operation during AC outages. Shutoff hardware sold separately. - Up to 5 years of battery life: Water Leak Sensor 4 includes 2 installed, replaceable AAA batteries per sensor for fewer battery changes under sinks and behind appliances. Life varies with usage, alarms and temperature. Check battery status in the app. - Plug, scan and place: Add sensors to your existing YoLink hub; a hub is required for app features. Scan device QR codes in the YoLink app, then place sensors near water heaters, sinks or washing machines. Top and bottom probes detect drips and pooling water. No sensor wiring or individual Wi-Fi pairing required. - One hub for your growing smart home: A YoLink hub supports 300+ YoLink devices. Choose from 100+ products, including leak sensors, shutoff controls, door and motion sensors, smoke detectors and lighting controls. Manage compatible devices in one app. Additional devices sold separately. - Designed in the USA, supported by YoLink: Get help with setup, troubleshooting and expansion from YoLink customer support. The app also lets you review alert history and set low-temperature warnings to help you respond to cold conditions. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0CHS5N68B | | Audible Noise | 105 db | | Battery Description | Alkaline | | Best Sellers Rank | #9,309 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #8 in Leak Detection Tools | | Brand | YoLink | | Built In Media | Batteries | | Color | 105 dB | | Compatible Devices | Smartphone, Tablet | | Control Method | App | | Customer Reviews | 4.7 4.7 out of 5 stars (1,833) 4.7 out of 5 stars | | Item Highlight | Leak and Freeze App Alerts, IP67, Up to 5-Year Battery, Works with IFTTT, LoRa YoLink Protocol Up to 2034 Feet, Hub Required | | Manufacturer | YoSmart | | Maximum Range | 2034 feet | | Mfr Part Number | 3YS7906 | | Model Name | 3 Leak Sensors | | Model Number | 3YS7906 | | Mounting Type | Tabletop Mount | | Number Of Batteries | 6 AAA batteries required.
