Smart Home System is the term that describes the intelligent control and monitoring of different home appliances to manage the home environment in an intelligent, safe and comfortable way. Home automation allows us to control home appliances like TV, Refrigerator, AC, fan, etc. Home automation not only refers to reduce human efforts but also plays vital role to save energy and time. The main objective of home automation is to help handicapped and old aged people it will facilitate them to control home appliances. In the present era smart phone market has been dominated by the Android operating system. Smart phones features made to communicate to any other devices using Bluetooth technology. Bluetooth wireless technology is built into billions of products, from cars and mobile phones to medical devices and computer s and even forks and toothbrushes. Bluetooth technology allows you to share voice, data, music, photos, videos and other information wirelessly between paired devices. It is an essential element for bringing everyday objects into the connected world. Home Automation System (HAS) has been designed for mobile phones having Android platform to automate an Bluetooth interfaced 8 bit AVR Microcontroller which controls a number of home appliances like lights, fans, bulbs and many more using relays. In houses, lamp switches normally located at a high location and it is hard to reach for the switches without help for kids and disable person including people who unable to move a lot due t o accident cases. These problems can be overcome by using the home Automation System Using Android Application & Bluetooth at home which is user friendly and cost efficient.

2. CONTENT
• Introduction
• Problem in Present Scenario
• Operation Principle
• Advantages
• Disadvantages
• Conclusion
• Future Scope
• References

3. INTRODUCTION
• Realize the concept of a smart home.
• Wireless home network.
• Appliances can communicate with with each other in
network.
• Use in a cost-effective manner .
• Provide secured network.

4. PROBLEMS IN PRESENT SCENARIO
• Complex wired network
• Time consuming
• Faults in power system
• Cost of electric system is high

5. OPERATION PRINCIPLE

6. The Major blocks:
1. Microcontroller (ATMEGA16A).
2. GSM
3. Bluetooth
4. LCD
5. Relay

7. ATMEGA16

8. Features for ATMEGA 16
• 32x8 general purpose working register
• 512 K Bytes EPROM
• Programming locks for software security
• Extensive on-chip Debug support
• 8-channel, 10-bit ADC
• Operating voltages: 4.5-5.5 V
• Speed Grades: 0-16 MHz

9. GSM MODEM

10. • SIM 900 is used for data applications.
• Offers features like Short Message Services (SMS),
Data Services (sending and receiving data files), Fax
Services and data file connectivity through wire is not
available or not possible.

11. BLUETOOTH MODULE
• HC-05 module is an easy to use bluetooth SPP (serial port protocol)
module , designed for transparent wireless serial connection setup.

12. RELAY
• Electricity flows through a coil, it becomes an
electromagnet.
• Attract the steel plate which is attached to a switch.
• So, relay acts as a switch.

13. OUTPUT

14. ADVANTAGES
• Bluetooth is cheap.
• GSM is easily available.
• Low energy consumption.
• Easy to handle, especially for handicapped people.
• Accessed from remote areas.

15. DISADVANTAGES
• Limited range for bluetooth
• Standard SMS charges may apply
• Need of strong network
• Bad network problem because of changing atmosphere.

16. FUTURE SCOPE
• To enlarge the range of connectivity Wi-Fi, 4G/5G, Li-Fi
• Android , Internet, etc.
• To monitor the activities around the home, security
cameras can be installed and controlled by the users
• It will improve the security of home

17. CONCLUSION
• The purpose of this is to use mobile phone’s
inbuilt Bluetooth, SMS facility and Bluetooth
serial module and GSM Modem for
automation of Home Appliances.
•The different hardware and software section
of our system is described.
