WS303 - LoRaWAN Leak Detection Sensor - Milesight

The Milesight WS303 is a compact LoRaWAN sensor designed to detect water leaks and conductive liquids. It can quickly send a remote alert while triggering a local alarm with its integrated buzzer.

Detection and Monitoring

The WS303 detects the presence of liquid via a dedicated probe. It is suitable for sensitive areas where a leak needs to be quickly identified: technical rooms, restrooms, server rooms, storage areas, or equipment exposed to water risk.

LoRaWAN Transmission

Alerts are transmitted via LoRaWAN Class A on the 868 MHz band. The sensor can be integrated into a LoRaWAN gateway and a compatible IoT platform to centralize alerts, monitor equipment status, and organize interventions.

Installation and Battery Life

The WS303 operates with a replaceable 590 mAh CR2450 lithium battery. Its NFC configuration via a mobile application simplifies commissioning. Its IP67 casing allows installation in environments exposed to humidity.

Applications

This sensor is suitable for Smart Building projects, preventive maintenance, and leak detection in professional buildings. It helps limit damage caused by leaks and speed up field interventions.
