Based on a research done by Bina Nusantara International University, an application is developed to monitor the
power usage of home electronic appliances (Geumpana, Koentjoro, & Widjaja, 2012). Two Arduino
microcontrollers are used for monitoring the power consumption and sending it directly to the Windows Azure
server, so it must be always connected to the internet in order to record the power consumption data. The capability
is limited to monitoring power consumption only without any controlling or diagnosing capability.
