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

Parent Projects

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

Similar shields

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.

CuteDigi Smart Outlet LCD Shield

ACS712 (current mesuring) + 16A TRIAC (switch) + LCD + 2 buttons interface The current is mesured with an invasive IC (ACS712). No voltage measuring?

emonTX (not a shield, standalone)

Current and voltage measurement options

Non-invasive AC external current sensor clamp + 9V Power adapter + Rectifier circuit

Non-invasive AC external current sensor clamp + 12V Power adapter + dedicated dsp chip (ADE7753)
