Netvox R718WB – Wireless LoRaWAN Water Leak Detector with Rope Sensor

Netvox’s wireless water leak detector with rope sensor detects the presence of water if any portion of the rope becomes wet. The status data is sent to the data centre via the LoRaWAN protocol at pre-programmed intervals in addition to the signal being sent when a leak is detected.


  • Wireless range of up to 10 km (depending on environment)
  • LoRaWAN Class A compatible
  • Frequency Hopping Spread Spectrum (FHSS)
  • Improved interference immunity
  • Improved power management for longer battery life
  • Encrypt-RF™ Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • Over-the-air updates (future)
  • Third-Party online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email (optional)
