The author says :

With some old Energy Meters it is not simple at all to convert the Power Consumption into digital datas. In my case I’ve used an old NXT Light Sensor from NXT Mindstorms, to measure the wheel mark of my Analog Energy Meter. One cycle is 1/75 KWh (13,33 Wh). To measure the mark of the wheel I’ve used an Arduino Mega, and to log and request the data I’ve used an Ethernet Shield with SD Card slot.
