WS303 is a tiny, mighty leakage detection sensor that detects water leaks and transmits an alarm using LoRaWAN® technology. With this low-power technology, WS303 can operate for up to 5 years on a 590mAh battery. Compliant with the Milesight D2D protocol, it can directly link with other Milesight devices to realise 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 locally via a built-in buzzer and remotely via a mobile app. Combined with a Milesight LoRaWAN®gateway, users can manage all sensor data remotely and visually.
