Development of a cellular based device controlling system via wireless cellular network/bluetooth

Abstract

In this paper we reveal a wireless controlling system to control home appliance to high power industrial machine via wireless cell phone network or bluetooth technology. Built-in bluetooth technology inside mobile phone has been used to send command signal when distance is within bluetooth communication range like inside a room likewise wireless cellular network used at what time the distance is long but this cost user for every command. Two Java supported handsets have been used in this controlling system, one at user end and another at device end that would be controlled by this system. J2ME based mobile application also has been developed for both end as user interface/command generator and command decoder. A microcontroller based switching circuit has been added with this system to switch the relay according to the command signal and finally whole system successfully tested in the libratory.
