I-Sense
|
|
-I-Grid uses ultra-low cost I-Sense™ monitors to capture and transmit power data through the Internet to a central server for display on the I-Grid website, as well as send event notification to monitor owners.
-The I-Grid eliminates the need for expensive hardware and software, reducing the cost of power monitoring from as much as $15,000 to under $750 per monitor.
