The next generation electronic industry shows infinite scope of excellence starting from the cutting edge tools of massive industrial applications, war front technological support, health appliances, space applications and consequently offers unlimited cost effective consumer electronics for daily life uses. The quest for incorporating higher number of applications in one easy accessible, portable and smarter platform has paved the path of nanotechnology in contemporary consumer electronics in every sphere of life. Now societies are quite concern about security measures adopted so far in residential buildings, offices, school-colleges, owing to the fact that with modern technological support no life should be vulnerable to fire like hazards. But statically these precautionary systems are much expensive. In such circumstances the authors here tender to design a novel low power consuming, economical nano device smoke detector alarm to be incorporated in residential security systems.
