Choose the Right Leak Sensor for You
YoLink offers two leak sensors for different needs. Water Leak Sensor 1 is a quiet, discreet option that relies on phone notifications. Water Leak Sensor 4 adds a loud built-in siren, making it ideal for high-risk areas like basements or garages. Both connect to the YoLink Hub for instant alerts.
5-Year Battery Life
Runs on 2 AAA batteries (included) for up to 5 years of nonstop leak protection.
LoRa Long-Range Signal
Stays connected up to 1/4 mile, even through walls and floors where WiFi fails.
IP66 Waterproof Build
Fully sealed design survives direct water contact, perfect for damp or flood-prone areas.
Smart Alerts & Integrations
