RA0711 Netvox LoRaWAN Wireless Liquid Level Sensor
The RA0711 is a wireless communication device that detects the depth of liquid. RA0711 detects the depth of liquid in the container. The wireless liquid level sensor uses a solid state, continuous (multilevel) fluid level sensor for measuring levels in water, non-corrosive water-based liquids and dry fluids (powders). The communication is fully compatible with LoRaWAN™ Protocol (Class A).
