Real-time energy monitor with Arduino and LabVIEW:
Arduino board that detects the led pulses and sends the data via the XBee module, and a PC that recive the data through a USB/Xbee module and processes the data with LabVIEW so you can prepare and study the consumption in a very instant.
Arduino sends two datas to the PC:
1 – Real time datas
2 – Average consumption measured in a time of 5 minutes.
Thanks Boris! Via the contact form.

A very, very expensive solution to the problem, but looks like a good learning exercise.
