Product Description

Introducing the Milesight WS303, a mini water leak detection sensor that detects the presence of leaks and raises alarms locally and remotely. With low power consumption, it can operate for 5 years on a single battery. The WS303 will sound an alarm and send a remote alert when a water leak, water spillage, or floor wetness occurs.

The WS303 sensor uses water conductivity to detect a minimum water level of 0.5 mm by forming a circuit with two small metal probes. (Other conductive liquids are also supported.)

Suitable for a wide range of applications, including:

  • Smart Homes & Building
  • Smart Offices & Facilities
  • Warehouses & Storage

Features

  • Immediate Warning Locally and Remotely
  • Unique Milesight D2D Communication
  • Up to 5 Years Battery Life with One Coin Cell Battery
