Automatic Porch Light, door, home appliance control system using PC via USB

Abstract

Optimization of costs of automation can be lowered by control of peripheral devices directly
from a private computer at the places where computers are already being used for other
purposes. All new-generation computers are incorporated with USB ports which can
accommodate an interface providing for vital digital inputs and outputs for the control of
peripherals. Even without tracing cables to the controlled device, the computer remains
under control whereas wireless technology allows dislocation of the executive part of the
interface. This application gives a path for an interface which enables wireless turning
‘on/off’ control of peripheral devices through USB computer port and also controls the
algorithm on computer that communicates with the executive module of the interface through
USB port and a wireless link.
