View source for Arduino Smart Plug Shield

This page is the development documentation platform of the Smart Plug Shield for Arduino.

== Parent Projects ==
*http://openenergymonitor.org/emon/input

== Design requirements ==
* Precise, easy calibration,  reduced size, Current and Voltage measuring system 
* Modular communication module: XBEE (jNode?, Etherner?, CAN?)
* Load ON/OFF or dimmer (10-12A Triac)
* Integrated 220V to 9V-5V power supply (ex. 220 to USB chargers > Switched-mode power supply?)
* Optional: RTC chip for having time stamps on the measurements.
* Optional: RGB LED / LCD for feedback

== Software Projects ==

===Arduino Energy Shield===
XBEE + RTC + ADE7753 (power calculation SPI or pulse comunication) + 1 Clamp input + 1 Transformer input. The current is mesured with a non-invasive AC external current sensor and the voltage with an external 12V adaptor.

===SEG meter===
XBEE + 6 Clamp input + 1 Transformer input
The current is mesured with a non-invasive AC external current sensor and the voltage with an external 12V adaptor.
