NETVOX Wireless Water Sensor R311W is a LoRaWAN device compatible with LoRaWAN protocol (ClassA). When the R311W sensor detects the leak, it will send an alarm message to the gateway. When the sensor detects no leaks, it will send a message that shows no leak to the gateway.

Principle of Operation

NETVOX Wireless Water Sensor is available to detect water leak at data center, engine room, boat blige...etc. The radio transmission is based on the new disruptive LoRa long range technology. R311W will transmit information and data to the server from application fields based on the desired behavior. The low battery consumption device is long lasting which ensures optimum usage.

Thanks to small sizes, they can be installed everywhere. They are wireless so they take up minimal floor space.The transmission is direct to a central center that can be programmed to trigger an alarm system.Thanks to innovation, these wireless sensors are more reliable and precise and they can detect several applications.

Example Applications

Data center and server room water monitoring
Document retention center monitoring
Basement water monitoring
Plumbing leak detection
Boat bilge monitoring
Storage monitoring
And many ..
