Wireless monitoring and driving system of household facilities for power consumption savings remotely controlled by Internet

Abstract

In this paper it is described a wireless monitoring smart system of household electrical facilities, with ZigBee/WiFi transceivers, able to measure the absorbed current from electrical loads, to calculate dissipated power and energy by means of PIC-based software and to display the calculated consumption values on web page opportunely 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 the 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 regulate the intensity of each light point for achieving different lighting scenarios. All functional tests, carried out on the realized PCB prototype, relative to the monitoring/driving of real house's electrical facilities, have yielded positive results.
