I am doing a project on industrial devices control using bluetooth.For this i have to give a one power point presentation. I am having some matter,but it does not enough
to give ppt.So i request you to give some more information for me.

with kind regards

Bluetooth is a wireless module that transfers data from dongle to bluetooth modem and modem to Bluetooth dongle. This module allows you to transmit and receive wireless data in serial format. It is an advanced technology that can be widely used today in mobile data exchange and within network communications such as modem to printer, etc. Allowing transparent bidirectional data communication. In our project we can simply use it to transmit wireless serial data to establish the connection between MCU or embedded project and PC. Our project is designed to control industrial devices remotely through Bluetooth wireless data transfer. Many industrial devices work on the A.C. The micro-controller can not directly drive the A.C loads, so we are using a relay unit for the A.C control. Here we control the relays through the micro-controller which in turn receives the input of the PC hyper terminal or .net c # application. The Bluetooth modem connects to the micro-controller in series with 9600 baud. The Bluetooth modem range is 10 meters with 2.4 GHz frequency. Blue Tooth The transmission power is 4dBm and the sensitivity is 84 dBm. Here in our project the Bluetooth modem acts as a receiver and the Bluetooth dongle acts as a transmitter that is connected to the USB port of the PC. In this way, we can control the appliances from a PC using the Bluetooth interface. Here we use an 8051 micro-controller with 5V DC power supply. Serial (UART) protocol is the main concern here. The heart of this project is the Bluetooth modem that works on serial protocol (UART). The micro-controller is interconnected with relays that are activated via transistor switching.
