Main aim of this project is to provide sms based tracking of different locations in the home while you are not at home.This project can also be used to monior the different signals conditions of the machines in factory or industry. A GPS module will be installed in the home which will transmit the status of different doors continuously after short intervals or when the status of any signal is changed. Location will be sent as a sms through gsm network. These messages will be received by another GSM module situated at some remote location. The purpose of this project is to monitor and control electrical devices (Analog and Digital) remotely using GSM modem/phone. The GSM modem provides the communication mechanism between the user and the microcontroller system by means of SMS messages.
User can have the condition of various signals attached at multiple electrical devices by recieving suitably formatted SMS message from the microcontroller based control system. These SMS commands are interpreted by microcontroller system and are transmitted to other remote mobile.
Function and methodoly
There are eight input devices attached to microcontroller, the input devices can be extended to 32 depending upon the need. But currently it has only eight inputs. The inputs can generated from from rad switches, IR transmitter and receiver or other magic switches. For security these should be implemented in such a way that these should be hidden. When any of the door is opened, coresponding switch is operated, microcontroller is contineously monitoring all eight switches, on finding the changed in status of the input from door, the microcontroller turns ON the security alarm for a few second. On the same time a SMS is sent to the remote mobile about the latest situation of the home security.
If no other switch is operated (door is not crossed) and door is re-closed on the alarm, then the security alarm will be OFF otherwise it will be ON repeatdidly and do send SMS contineously to owner about home or office security.
