Arduino Power Panel
« on: January 22, 2013, 01:26:34 pm »
I put together an energy monitoring system using an Arduino Micro, it is based off of openenergymonitor.org designs . You can find specifications for the circuit and download the libraries for Arduino from their website. The code I am posting is calibrated for the micro 40 solid core current transformers from Brultechs store (http://www.brultech.com/home/store/product.php?id_product=45) . The system is only able to monitor Apparent power at this point, I plan to upgrade the design with an AC to AC adapter to allow monitoring of the mains voltage to allow for additional power calculation (True Power, power factor...etc). To install the plugin on the vera, upload the three files (I_PowerPanel1.xml, D_PowerPanel1.xml, and D_PowerPanel1.json) to the vera unit and then create a device, with a device file of D_PowerPanel1.xml and an implementation file of I_PowerPanel1.xml. I am running this on a Vera Lite, running Ui5 version 1.5.408. I have also posted my Arduino sketch (RMS_Power_With_Constant_Voltage.txt)

bitdropper,

Thanks for your efforts in offering another alternative to monitor power consumption. I am now starting to look at monitor my power usage and this looks interesting. Also looking at the brultech greeneye kit as well.

Would this work to monitor 220V?  I'm trying to monitor a pool heater to understand how expensive it is to have on for a week (at various temperatures).  I've just started using Arudino to put temperature sensors on the pool intake and output pipes.  Can't seem to find an energy sensor for 220V.  thanks.

It can be made to work with 220V mostly with software changes. You can start at http://openenergymonitor.org/ to get an idea of how to connect the current transformers and download the arduino libraries. Also, look specifically at these links http://openenergymonitor.org/emon/node/2533http://www.desert-home.com/p/test-html-code.html they write about monitoring 220V. Let me know if you have any other questions.
