Communication Technology
The AquaSens Water Meter employs cutting-edge communication technology, LoRaWAN which provides low power consumption as well as long range signal propagation to enable real-time control and monitoring. The meter operates as a LoRaWAN Class A device.
Our smart gateway receives near real-time data from all the valves within range, converts the raw data into an easy-to-use JSON format, and then publishes it using MQTT protocol. Data can be sent to any local or cloud MQTT broker via Ethernet, LTE (4G), or WIFI.
