Why Bluetooth?

Bluetooth is a wireless short-range communications technology facilitating data transmissions over short distances from set cellular devices, creating wireless personal area sites (WPANs). The objective behind the growth of Bluetooth was the establishment of a distinct digital wireless standard protocol, capable of linking multiple devices and conquering issues arising from synchronization of the devices. Devices such as cellular phone, laptops, printers, computer systems, GPS (Global Positioning System receivers), surveillance cameras and unlicensed Industrial, Scientific, and Medical (ISM) developing a rate of recurrence of 2. 4 GHz provides a way to add and exchange information between short-range radio frequency bandwidth.

Bluetooth is the method of standard communication protocols at first created for low power consumption, through a brief range like (1m, 10m and 100m) predicated on low-cost transceiver microchips in all devices. It permits these devices to communicate everyone with in the number. The devices used in radio marketing communications system, won't need to be within line of sight with the other person and even in other rooms, as long as the signal received for transmitting is powerful sufficient.

Bluetooth was conceived in the beginning by Ericsson, the Bluetooth standard has been implemented by many companies worldwide. A Bluetooth chip is designed to replace cables by firmly taking the info normally completed by the cable connection and transmitting it at a special regularity to a receiver Bluetooth chip, that will then supply the information received to the computer, telephone, etc.

Interest in Bluetooth has been increasing over previous couple of years and consumers may be prepared to encounter an plethora of Bluetooth-enabled products as many companies have invested in this technology. Companies such a Toshiba and Sony are planning to build Bluetooth into almost all of the merchandise they make, including consumer electronic home appliances, for example toasters, video tutorial recorders and microwave ovens.

Maximum work was allocated to the Bluetooth technology that aimed at promoting interoperability. To the finish of Bluetooth Special Interest Group (SIG) has produced over 500 webpages of profile (posted in amount 2 from the version 1. 1 requirements). So, because of the wide utilization of Bluetooth in many applications and also taking into consideration the security factors in Bluetooth we choose this job using Bluetooth.

Functional Description:

In this project we are sending the signal through mobile. So, we aren't using any wiring, it comes under cellular communication. We are experiencing two modules. One is the transmitter which is utilized to transfer the transmission. Here the transmitter is nothing but mobile phone through which we send orders to PC. To receive the transmitted signal (command) a Bluetooth dongle is attached to pc which works as receiver.
