Stop Leaks, Avoid Further Damage
Introducing the 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. It's ideal for smart offices, buildings, houses, etc.
WS303 will sound an alarm and send a remote alert when water leakage occurs.
The WS303 sensor uses water conductivity to detect a minimum water level of 0.5 mm by forming a circuit with two little metal probes. (Other conductive liquids are also supported.)
Milesight D2D (Device to Device) communication protocol featuring LoRa® enables the communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.
To make it right and easy, Milesight Smart Restroom Solution provides IoT insights into the status of cleanliness and hygiene.

The compact design makes it easy to mount on a surface or wall as needed without wiring.
The WS303 is powered by a long-lasting coin cell battery that can last up to 5 years. This ensures uninterrupted usage and eliminates the need for frequent battery replacements.
