GSM Based Home Automation

Abstract

Mobile technology has been one of the most dynamic technologies in the world for the last two decades. The daily use of mobiles in any person’s life is immense and the growth expected in this sector is exponential. The basic idea of this project has been derived from the same fact after analyzing the future scope and prospects of this technology. GSM technology has been the fore-runner compared to CDMA technology, which are both offshoots of mobile technology. Roughly eighty percent of the world’s mobile phones work on GSM as compared almost twenty percent working on CDMA. Our aim is to construct a GSM based digital lock code system having 10 digit password securities and controlling various electrical appliances using microcontroller 8051. For a system to be dynamic, a mobile phone is used to receive the code from another mobile from any location across the world. When a correct code is received we can control our devices or appliances from remote location.
