Monitoring Energy usage with the LED Pulse Sensor from Crucible Technologies

With winter coming, and all the energy scares in the news, I was keen to start monitoring the power we were using. I had always intended designing my own system with the LED Pulse Sensor and the Raspberry Pi, but had never got round to it. So I thought I'd quickly rig up soemthing using the Meter Logger from Crucible Technologies. Took me around half an hour to set it all up.
