i have to use a sensor for hurdl detection in auto vaccum cleaner....if anyone know about it then please help me on sabahat_ali88@yahoo.com

Is it because this has been set as your school assignment?
If it is then, surely, part of your assignment is to do the basic research to find what sensors are available?
