NB-IoT Water Leakage Sensor

A small, battery-powered leak detector that watches under sinks, behind appliances, in restaurant service areas, engine rooms and server rooms — and tells you the moment water shows up, before small leaks become expensive repairs.

WSMART water leakage sensor mounted in a server room

Long-life battery operation

No mains wiring. Continuous leak monitoring with battery life up to 4 years.

Two detection options

A 2-pin contact probe for point leaks, or a sensing rope for linear coverage up to 100 meters.

Adjustable sensitivity

Tune sensitivity to your site. Reduce false alarms while keeping reliable detection.

Instant multi-channel alerts

The moment water is detected, you get an app push and email — wherever you are.

Simple install & data access

Quick mounting and instant cloud onboarding. Review leak events and export history from the app or web dashboard.

Compact & discreet

Small enough to sit quietly under sinks and behind appliances, out of sight.
