European Utility Week Communication Power Management Sensors

ROHM Semiconductor provides a wide range of products suitable for Smart Metering & Smart Home applications

Smart Metering & Smart Home are important parts of the Smart Grid which attempts to predict and intelligently respond to the behaviour of energy suppliers and consumers in order to efficiently deliver reliable, economic, and sustainable services.

In order to achieve this the traditional meters like electricity, gas, heat and water meters will be connected using various wireless and wired communication technologies.

ROHM Semiconductor provides a wide range of products suitable for Smart Metering & Smart Home applications and will showcase its products at Booth 3H62 of European Utility Week in Barcelona, Spain from Nov. 15-17, 2016.

We would be happy to meet you at European Utility Week 2016!
