BLUEHOME

About the project
BlueHome is a home automation system wherein each one can check, and control their house-hold appliances using bluetooth enabled mobile phone. This system works through BlueTooth technology. The user can control his/her appliances using a Bluetooth mobile. Our project has the following modules.
(a) Mobile Unit
The Mobile Unit is sub-divided into two categories. They are:
1. Device Discovery Unit
2. Device Communication Unit
The Mobile Unit consists of a Bluetooth enabled mobile phone. This device acts as a source end wherein the user can send the control signal to his/her home appliances.
The Device Discovery Unit deals with detecting the Bluetooth devices in its proximity. In our project, we are using a Bluetooth dongle for communication. i.e, control signals are sent to control unit via dongle. This section includes detecting Bluetooth devices using java Bluetooth APIs. Once the devices are detected, a communication path is established between them (for later data transfers).
The Device Communication Unit is involved in further communication between Bluetooth devices once they are discovered. This unit is also developed using java Bluetooth APIs.
(b) Receiver End
The Receiver end is seialBlue embedded device. It receives the control signal sent by user via his/her Bluetooth mobile. It then transfers the received data to a microcontroller,which is serially connected, for further device contol.
(c ) Control Unit
This is the hardware end consisting of a micro controller along with its supporting devices. This unit receives data from seialBlue embedded device. This PIC is pre-programmed in such way to identify control signals and it automatically controls devices as accordingly.
Purpose of project
The purpose of the project is to enable a user to control the home devices remotely.
