LoRaWAN Dual-mode Meter Reading Module
The HAC-MLLW LoRaWAN dual-mode wireless meter reading module is developed based on the LoRaWAN Alliance standard protocol, with a star network topology. The gateway is connected to the data management platform through a standard IP link, and the terminal device communicates with one or more fixed gateways through the LoRaWAN Class A standard protocol.
The system integrates LoRaWAN fixed wireless wide area network meter reading and LoRa Walk-by wireless handheld supplementary reading. The handhelds can be used for wireless remote supplementary reading, parameter setting, real-time valve control, single-point reading and broadcast meter reading for the meters in the signal blind area. The system is designed with low power consumption and long distance of supplementary reading. The meter terminal supports various measurement methods such as non-magnetic inductance, non-magnetic coil, ultrasonic measurement, Hall sensor, magnetoresistance and reed switch.
