Wireless smart system for monitoring and driving of household electrical facilities remotely controlled by Internet

Abstract

This paper describes a wireless monitoring smart system of household electrical facilities, with ZigBee/WiFi transceivers, able to detect absorbed current from electrical loads, to calculate dissipated power and energy by means of PIC-based software and to view the calculated consumption values on web page properly realized for user's remote control. Depending on light/presence sensors' signal, the realized system can switch on/off the monitored electrical loads for obtaining energy savings and user satisfaction. Also by sending DALI-standard commands to slave loads (e.g lighting facilities based on LEDs), the user can monitor, remotely by using a tablet/smartphone connected to internet, the operation's state and adjust the light intensity of each light point for achieving different lighting scenarios.
