Milesight Mini Leak Detection Sensor WS303
WS303 is a tiny and mighty leakage detection sensor for detecting the presence of water leaks and transmitting an alarm using LoRaWAN® technology. With this low power consumption technology, WS303 can work for up to 5 years with a 590mAh battery. Compliant with the 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 the Milesight LoRaWAN gateway and Milesight IoT Cloud, users can manage all sensor data remotely and visually.
