FUTURE ASPECTS

OF PROJECT We are now at the middle stage of the project.

We are planning to imply the optical

sensor to control illumination . We are also planning to imply a visit based

counter in our project.

All these components will help to modify ourproject more & more.

::CONCLUSION::

Our project has both advantages & disadvantages,though we have selected this project. I t wil l help to

save the energy for our future generation. I t wil l

also help to enrich our knowledge on embedded

system. This project can be implemented inschools, colleges, off ices & also many other

places. Now we are trying to modify our project

more & more.
