Milesight WS303 Mini Leak Detection Sensor

Smart Water Leak Detection Solution

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.

Immediate Warning
Against Water Damage

WS303 will sound an alarm and send a remote alert when water leak, water spillage, or floor wetness occurs.

Sensitivity That Exceeds Expectations

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 Communication

Milesight D2D (Device to Device) communication protocol featuring LoRa enables the communication among different Milesight LoRaWAN® node devices without a LoRaWAN gateway.

Smart Restroom Solution

To make it right and easy, Milesight Smart Restroom Solution provides IoT insights into the status of cleanliness and hygiene.

Power Failure Alarm

WS303 includes capacitor storage to trigger a power failure alarm.

Ensuring Device Safety with Robust Protection

Utilizes gold-plated probes and stainless steel screws to prevent corrosion.
Equipped with IP67-rated enclosure to fit into more application scenarios.

Flexible and Effortless Installation

The compact design makes it easy to mount on a surface or wall as needed without wiring.

Ultra Low Power Consumption

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.
