Home power consumption measuring unit

In Norway we have a LED in our home fuse boxes that flashes a defined number of times per kW, this unit measures the home power consumption by counting those pulses. This is calculated into kW and can be read from a computer over the serial interface. In addition to this unit you will need a sensor to read the LED, that is not covered in this project. It is important that this sensor is accurate to get precise values.
