The RA0711 is a LoRaWAN water level sensor which 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)
We can supply third-party online wireless sensor monitoring and notification system to view data and set alerts via SMS text and email.
Ask us about our zero-touch provisioning service, this sensor can be supplied pre-configured and ready to go.
