Password operated device control using mobile communication
- 1. Embedded systems Ph:7842522786 9948887244 Password operated device Control using mobile communication ABSTRACT AIM: The main objective of this project is we are going to develop an embedded system, which will control all the devices with command (password) from a Remote device (our mobile) through GSM communication. IMPLEMENTATION: This project is implemented on 8051 based At89s52 developed board interfaced with GSM modem, relay of connecting the devices, LCD for displaying the data.

Anybody can do controlling of devices. But here the thing is controlling devices is restricted to particular persons who are provided with the password. The persons who know the password only can control the devices by sending password as message. In this project we are using at89s52 microcontroller for controlling the equipments in the home. GSM modem is used to communicate and respond to the remote commands and those commands are sent to the the micro controller via RS 232 communication means MAX232 chip. This automation system can also be used for industrial applications with small modifications. SOFTWARE: Embedded ‘C’ RIDE to write code ISP to burn the chip HARDWARE: At89s52 based our own developed board Power Supply GSM module RELAY ADVANTAGES: Low cost, automated operation, Low Power consumption. skesystems@gmail.com Vijayawada Hyderabad Page 3
