Arduino home energy monitor.
Arduino energy monitor ethernet.
The energy monitor shield is primarily designed to be used for building energy monitoring systems like a customised multimeter but can be integrated into existing systems for enhanced functionality or circuit security.
The sketch is the software that runs on the arduino.
Ct sensors interfacing with an arduino.
Main unit assembly installed energy monitor measurement board assembly.
The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor.
The ethernet unit is connected to the router the small box on top of the larger box houses the wireless xbee link.
The project consists of two parts a server and a client both made with an arduino and a couple of ethernet shields.
It is not only capable of monitoring energy usage but can also interact with compatible arduino boards and shields allowing.
Here are the complete arduino sketches for the main and ethernet units.
The code is shown in the attached images here is the link to download the energy meter code.
And here s a short description of how to build an enclosure.
They are made up of the stand alone sketches from each section above.
It is inspired to open energy monitor of which uses a slightly modified version of emontx v2.
Because your setup ct resistors and input voltage may be different there is a scaling factor in the sketch which you will need to change before you will get.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
The energy monitor can calculate real power apparent power power factor rms voltage rms current.
All the calculations are done in the digital domain on an arduino.
For the rest we use dhcp ip address and such.
The resulting energy monitoring shield has a.
Upload the arduino sketch.
Assemble the components per the diagram above.
1x 9v ac ac power adapter 1x 100kohm resistor for step down voltage divider.
Below is a screenshot of the web based graphing that can be seen live here.
