Objective of the project:

This project is an extension to our minor project “Automatic energy saving lighting

system”. In the minor project we included automation of lights and fans according to the

natural light intensity and ambient temperature inside the room.

This project deals with the designing of an automatic control system for the room that

increases flexibility and comfort for users and decreases cost by reducing the energy

consumption. By inculcating the use of non-conventional energy sources the overall

efficiency of this system is also increased thereby making the system much more reliable

and independent. The basic aim of extending this project is to make it more energy

efficient and to include the automation of windows of the room as well.

Project summary:

Circuit1: Automatic control of lights inside the room according to the natural light

intensity.

Circuit2: Automatic control of fan according to the ambient temperature inside the room.

Circuit3: Automatic control of windows during rain outside the room:

During rain outside the room the circuit attached to the circuit will be short circuited and

it will connect the stepper motor connected in the circuit directly to the supply. This

motor will close the motor so as to prevent the rain water from entering in the room as

per the requirement. The control of the motor can be achieved via programming a

microcontroller. The operation of the window can be made manual as well when

automatic control is not preferred.

By including solar cell for dc supply to replace the battery in the above circuits we

can make this project more dependable.

The solar tracking system can also include a tracking mechanism so as to improve its

performance throughout the day.
