BLUETOOTH AUTOMATION SYSTEM

INTRODUCATION

1. All the electric appliances will be controlled automatically.

2. We can control many different devices like AC, projectors, lights, fans, air conditioners, television e.t.c

3. A central controlling unit will be established.

4. The interface for the data transmission would be the Bluetooth.

BLUETOOTH TRANSMITTER

1. USB Bluetooth transmitter

2. Class 2

3. Range 20m

4. Data rate up to 3Mbps

5. Frequency 2.4GHz

6. Version 2.0

7. We can increase the range by using class 1 Bluetooth transmitter.

BLUETOOTH MODULE

1. The bluetooth module WT11-A-A1 is Used.

2. This bluetooth module receives the data which is send from the bluetooth transmitter .

3. After receiving the data it decodes it for the microcontroller.

SPECIFICATION

WT11-A-A1

Bluetooth 2.0-2.1

Class 1

Data Rate 3000 kbps Frequency 2.4 GHz

Range 250 M

8MB of integrated flash memory

MICRO CONTROLLER

1. Microcontroller is an intelligent device and hence will be responsible for the decision making.

2. It will receive the data from the computer via wireless link.

3. It will then decode the data and look for the respective command.

4. That command will be sent to the output port .

1. ROM 4 Kbyte 2. RAM 128 byte

3. I/O Lines 32

4. Ports 4

5. VCC +5Volts

6. TTL Logic Use
