2 OVERVIEW
The Energy Monitoring Hub (EMH) is a data acquisition system which provides owners and managers of
commercial and industrial facilities with a cost-effective means of gathering crucial information in a timely
manner. The DAS footprint and industrial temperature range makes this a perfect solution for embedded
applications. Reduce development time and speed up integration by collecting and distributing energy
information directly from your equipment.
