This document presents a home automation project involving Bluetooth control of appliances. A circuit diagram shows a microcontroller connected to relays, a Bluetooth module, and a lamp. The microcontroller code is programmed using Kiel software and burned to the chip. When paired with an Android device via Bluetooth, appliances can be switched on or off remotely by sending data. Potential applications discussed include lighting control, HVAC control, security cameras, and presence simulation for vacant homes. Biometrics and touchscreen security systems are also mentioned as parts of home automation.

4. 1. PCB DIAGRAM

5. • A printed circuit board, or PCB, is used to
mechanically support and electrically connect
electronic components using conductive
pathways, tracks or signal traces etched from
copper sheets laminated onto a non-conductive
substrate.
• When the board has only copper tracks and
features, and no circuit elements such as
capacitors, resistors or active devices have been
manufactured into the actual substrate of the
board, it is more correctly referred to as printed
wiring board (PWB) or etched wiring board.

6. 2. CIRCUIT DIAGRAM

7. 1.)The above diagram shows a microcontroller , 3
relays, a Bluetooth serial module and a lamp.
2.) The microcontroller is a PIC microcontroller and
it requires a 5 volt DC supply.
3.) We can use 9V DC battery or 12V, 1A adapter to
provide the supply to the circuit. For the above
circuit additionally you need to connect reset
circuit and crystal circuit to the controller to work
properly.
.

8. 4.) Bluetooth module TX and RX pins are
connected to the RXD and TXD pins of controller

9. 6.) Vcc pin is connected to the 5V and GND pin is
connected to ground. Controller communicates
with Bluetooth module using serial
communication (UART protocol).
7.) Use a baud rate of 9600 to communicate with
Bluetooth. If you want to change the Bluetooth
name and password then you need to use
Bluetooth AT commands.

11. PRINCIPLE
This project aims at controlling home appliances
using Bluetooth serial module.
Bluetooth has always been meant for sharing
purposes.
But this project adds an advantage of bluetooth
by controlling home appliances.
Bluetooth serial module is connected to the
microcontroller circuit and it is further connected
to the relay.
We connect appliance to the relay and operate it.

12. How Bluetooth Controlled Electronic Home
Appliances Circuit Works?
1.) Write the program to the project in Kiel software and create
hex file
2.) Burn program to the controller with help of flash magic.
3.) Now give the connections as per the circuit diagram.
4.) While making the connections, ensure that there is no any
common connection between DC and AC supplies.
5.) Use 5V power supply circuit to provide regulated 5V DC to the
microcontroller.
6.) Switch on the both AC and DC supplies.
7.) Now relay output pins gets 12v so do not touch the load
connected pins.
8.) Install Bluetooth apk file in android device.
9.) Now pair android device with Bluetooth module.
10.) Send data to switch on the electrical loads.

14. Control TV, Garage Door,
anything you want!!
• Deadbolt Control • I-phone Apps/Controller
Control TV, Garage Door,
anything you want!!

15. Green Building and Safe Building
• Electricity consumption
management
– Lighting control
• Regulated according to
ambient light
• Natural Light
• HVAC Control
– Shades/Curtain control
• Security
– Connections to
cameras, alarms
• Example: Flashing all
lights if alarm goes
off.
• Flood warning

16. Vacant Home Capabilities:
• Feed and watch pets
• Water plants
– Interior and Exterior
• Presence Simulation
– Lighting, TV, anything – pre-
programmed schedule

18. BIOMETRICS

19. BIOMETRICS
• The BIOMETRICS is a part of
automation , it is a security system
that can unlocked only by finger
prints or eye retina saved in system.
• Master touch and LCD used security
system is also a part of automation.
