This demo implements a power monitoring application that uploads data to Google PowerMeter. In this application, actual power consumption data is obtained from a PIC18F87J72 Energy Monitoring PICtail Plus Daughter Board.
Google, Inc. has deprecated Google PowerMeter and expressed its intent to remove access to it on September 16, 2011.
Because of this development, Microchip Technology has removed the Google PowerMeter demo projects from the Microchip Application Libraries distribution. To obtain Microchip's Google PowerMeter reference implementation, please download the archived Microchip Application Libraries installation from June, 2011 from www.microchip.com/mla.
This Energy Monitoring demo has been modified to remove its Google PowerMeter upload features. However, the energy measurements made by the PICtail can still be viewed on the demo board-hosted web page.
The PC GUI for the Energy Monitoring PICtail can be obtained from:
