- 1. Touch Screen based Home Automation System Project Guide- Prof. G. K. Andurkar Prepared by- Dhiraj M. Bhalerao Chetan S. Chavan Akshay R. Fiske
- 2. Introduction What is Automation - is the use of control systems and information technology to control equipment, industrial machinery and processes, reducing the need for human intervention. Use of Automation- 1. Office automation 2. Home automation 3. Power automation
- 3. What is Home Automation To control basic home functions and features remotely Different method of Home automation- 1. Remote control 2. GSM control 3. WIFI 4. Bluetooth
- 4. Project Aim The aim of this project is to design and construct a home automation system that will remotely switch on or off any household appliance connected to it, using a microcontroller The major building blocks of this project are - 1. Regulated power supply with voltage regulator. 2. Touch screen sensor. 3. Microcontroller 4. Appliances to be controlled
- 5. Hardware Requirements: Power Supply Block Microcontroller At89c51 Touch Panel Rf Transmitter & Rf Receiver (Ht12e/Ht12d) Opto-Isolator Triac Regulators Crystal Oscillator Diodes Resistors Capacitors
- 6. Software Requirements: Keil compiler Languages: Embedded C or Assembly
- 8. RF Transmitter and Receiver: RF modules are divided into three groups, RF transmitter module, RF receiver module and RF transceiver module 433MHz ASK transmitter and receiver is used for the remote control.
- 9. Opto-isolator: Opto-coupler MOC3061/63, A LED SCR Type Combination. Opto Coupler Is A Six Pin IC. Additionally While Using This IC With Microcontroller, One Led Can Be Connected In Series With IC Resulted In Indicate. When High Power Is Given By The Micro Controller Such That We Can Know That The Current Is Flowing In Internal LED Of The Opto- IC. When Logic High Is Given Current Flows Through Led From Pin 1 To 2. So In This Process LED Light Falls On SCR Causing 6 And 4 To Close Only At The Zero Cross Of The Supply Voltage.
- 10. TRIAC: Triode for Alternating Current (TRIAC), is a generalized trade name for an electronic component which can conduct current in either direction when it is triggered (turned on). It is formally called a bidirectional triode thyristor or bilateral triode thyristor.
- 11. Block Diagram:
- 13. APPLICATIONS Used in the range of 100-150 meters . Installation of system is simple. Uses wireless technology.
- 14. DRAWBACKS Used for the load upto 200 W only.
- 15. Conclusions: Wireless technology improves convenience. Simple , reliable.
