4.Working Principle
The principle of LoRaWAN electricity meter is to use LoRaWAN wireless communication technology to transmit electricity consumption data from the meter to a central server or gateway. The meter is equipped with a LoRaWAN module that sends data packets containing the electricity consumption information at regular intervals. The gateway receives the data packets and forwards them to the central server for processing and analysis. This allows for remote monitoring and management of electricity consumption, enabling utilities to optimize their operations and improve customer service. LoRaWAN technology is known for its low power consumption, long range, and secure communication, making it an ideal solution for smart metering applications.
