WLS316

Water Leakage Sensor

ZigBee 3.0 water leakage sensor with immediate alerting, two AAA batteries and smart device linkage for server rooms, warehouses and apartments.

Overview

The WLS316 is a ZigBee 3.0 water leakage sensor. When water reaches the sensing point it reports immediately — the normal heartbeat is once an hour — so a leak is signaled while it is still a small puddle rather than after it has reached the floor below.

Where It Is Used

  • Server rooms and telecom cabinets — under raised floors and at air-conditioning drain points
  • Warehouses and storage areas — under sprinkler risers, near loading doors
  • Apartments and rental units — under sinks, beside water heaters, behind washing machines
  • Hotel plant rooms and guest bathrooms — the same sensor covers both, without new wiring

How It Behaves

SituationWhat the sensor does
Water detectedReports immediately over ZigBee 3.0
Dry (normal state)Reports once an hour — a heartbeat, not silence
Network unavailableKeeps detecting; the state is re-sent when the network returns
BatteryTwo AAA cells (DC 3V), no mains wiring required

Placement Notes

  • One sensor per point where water can collect. A wall-mounted unit covers the area around it; a plant room with several water sources needs one at each, not one for the room.
  • Put it where the water arrives first — under the unit, at the drain, at the low corner of a raised floor.
  • Wireless matters here. Because it is battery-powered and needs no cabling, it can go where a wired leak detector cannot economically reach.

Key Features

  • ZigBee 3.0
  • Water leakage detection
  • Low power consumption

Frequently Asked Questions

What does the WLS316 detect?
Water leakage, with notifications from the mobile app.
How fast does it report?
When triggered it reports immediately; when untriggered it reports once an hour.
How is it powered?
DC 3V with two AAA batteries.
How can it be mounted?
Tabletop stand or wall mounting.
Does it integrate with other devices?
Yes — linkage with smart devices.
How many do I need for one room?
One per point where water can collect. A wall-mounted unit covers the floor area around it, so a plant room with several units needs one at each — not one for the whole room.
Does it need mains power or wiring?
No. It runs on two AAA batteries and reports over ZigBee 3.0, so it can be placed where there is no socket — under a raised floor, behind a rack or beside a water heater.
What happens if the network is down when it triggers?
The sensor reports on trigger and repeats hourly while untriggered, so the state is re-sent as soon as the network is available again. The device itself needs no cloud connection to detect water.
