WS303 Mini Leak Detection Sensor is a tiny and mighty leakage detection sensor for detecting presence of water leaks and transmitting an alarm using LoRaWAN^® technology. With this low power consumption technology, WS303 Mini Leak Detection Sensor can work up to 5 years with a 590mAh battery. Compliant with Milesight D2D protocol, it can directly link with other Milesight devices to realize danger prevention and effectively prevent unnecessary loss.

The wire-free WS303 can be easily used in smart offices, buildings, and houses. Users can receive real-time alarms via a built-in buzzer locally and a mobile App remotely. Combining with Milesight LoRaWAN^® gateway and Milesight IoT Cloud, users can manage all sensor data remotely and visually.

Smart Water Leak Detection Solution

Introducing WS303, the 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 leakage 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.

Lower Latency
Less than 1 Second Response Time
Secure Transmission
Reduce Investment Cost

Power Failure Alarm

WS303 includes capacitor storage to trigger a power failure alarm.
