The Milesight WS303 is a small LoRaWAN leak sensor for the places leaks usually start: under sinks, beside water heaters, below air-conditioning units and inside comms cabinets. It sits flat on the floor and alarms once conductive liquid reaches 0.5 mm.
- Local and remote alarm. A built-in buzzer sounds on site while the LoRaWAN alert goes to your platform.
- No wiring. Replaceable CR2450 coin cell, up to 5 years (based on one hour of leakage per week at 25 °C), IP67, 63 × 63 × 14 mm.
- Direct action. Milesight D2D lets it trigger another Milesight device directly, without going through a gateway.
Works with standard LoRaWAN gateways and network servers, such as the Milesight UG65 or UG67, with alerts and dashboards on IoT Factory. Set up by NFC with the Milesight ToolBox app.
