Smart Meter Success Story

WIZnet’s Germany distributor, DacomWest, has successfully applied the WIZ120SR into the smart metering application. Meters with GPIO, UART, or SPI interfaces can use the WIZ120SR to enable Ethernet connectivity.

The diagram below shows the implementation of the Smart metering application.

The WIZ120SR is applied at the client side of the application. The meter will periodically send data via Ethernet to the server which stores all the records.
