This document presents a PLC based home automation system. The system allows appliances like fans, lights, doors, and water tanks to operate automatically according to different sensors without the need for manual switches. The goals of the system are to make the room more user-friendly, efficient, and reliable while reducing energy consumption. The system can be extended to control additional appliances and systems for home automation and would be helpful for people with physical challenges or disabilities.

2. INTRODUCTION
• PLC is one of the mostly used controllers as it is
easy to operate and controls task according to the
program which is already fixed. So here is a room
where there’s no need to operate the appliances
through switches.
• The fans operate automatically according to
temperature and lights get turned ON according to
the intensity of light signal .
• The door operate automatically according to push
button and water is filled in the tank according to
float switch

4. BASIC APPROACH FOR SMART HOME
 To design and develop smart room which is user
friendly
 To understand the energy consumption associated
With room and to reduce it.
 To use the most appropriate hardware components
that would make the room more efficient and reliable.

6. Conclusion
• The proposed system can be extended to include many
number of other appliances or systems of building or home
automation like water sprinklers, ventilation systems ,burglar
alarm and many more
• The proposed system will be very helpful for physically
challenged and home bound elderly people as the desired
control of appliances can be made possible from a fixed central
location.
• By using GSM/GPRS or by simple transmitter and receiver
circuit remote control of the appliances is possible which will
further enhance the utility of the proposed system.
