Calinmeter Prepaid Smart Micro Grid System Multi Tariff Kwh Meter Single Phase LORA WAN
Calinmeter Prepaid Smart Micro Grid System Multi Tariff Kwh Meter Single Phase LORA WAN
A PLC (Power Line Communication) electricity meter is a device that measures electrical consumption and communicates data over power lines. This technology allows for the transmission of data without the need for additional wiring, utilizing existing electrical infrastructure to send information about energy usage back to a central system.
