WS303 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 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 the WS303, a 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 leak, water spillage, or floor wetness 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

Smart restroom solution

• To make it right and easy, Milesight Smart Restroom Solution provides IoT insights into the status of cleanliness and hygiene.

Power failure alarm

• WS303 includes capacitor storage to trigger a power failure alarm.

Ensuring device safety with robust protection

• utilizes gold-plated probes and stainless steel screws to prevent corrosion.
• equipped with IP67-rated enclosure to fit into more application scenarios

Flexible and effortless installation

• The compact design makes it easy to mount on a surface or wall as needed without wiring.

Ultra low power consumption

• The WS303 is powered by a long-lasting coin cell battery that can last up to 5 years. This ensures uninterrupted usage and eliminates the need for frequent battery replacements.
