JimboZA:
That's a completely trivial hobbyist project, not worthy of an ECE final year project for graduation. Every aspect of that project can be lifted from this site somewhere or other.
I agree with JimboZA.
In this project is an opportunity, however. Not many (trivial hobbyist or otherwise) Home Automation or Security solutions deal with the problem of detecting 'presence' if there is no motion (e.g. "did she fall asleep in her chair or did she leave the room?" or, "did my son enter the room or my dog?").
there are opportunities like that in your project...
