Netvox RA0711 LoRaWAN Liquid Level Sensor

The RA0711 is a wireless communication device that detects the depth of liquid. The wireless liquid level sensor uses a solid state, continuous (multi-level) fluid level sensor for measuring levels in water, non-corrosive water based liquids and powders.


  • 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)
  • Battery Life of up to 5 years (determined by sensor reporting frequency and other variables)
  • 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)
