Arduino_power_monitor
A project to monitor the electricity used at my house. Includes the code for the arduino and a schematic of the additional circuitry.
My first blog post was "Monitoring my house power with an Arduino and Perl" at http://www.martin-evans.me.uk/node/86. There are additions "New data shield" at http://martin-evans.me.uk/node/88 and then my final version "Version 2 electricty meter power logging" at http://martin-evans.me.uk/node/94.
The files in this repository are:
meter_reader_schematic1.png My first got at a meter reader before I got a data shield. I used meter.pl to log to a file the power usage.
meter1.pde arduino script which matches schematic 1 and meter1.pl.
meter.pl The Perl script to read the power usage from the arduino serial port.
meter_reader_schematic2.png My current schematic which matches the code in meter2.pde.
meter2.pde arduino script which matches schematic 2 but needs a data shield and an SD card.
usage.pl Read data loaded into database and create a csv of our usage.
