DESIGN AND CONSTRUCTION OF A GSM MODEM/PHONE  MONITOR AND CONTROL ELECTRICAL DEVICES

DESIGN AND CONSTRUCTION OF A GSM MODEM/PHONE  MONITOR AND CONTROL ELECTRICAL DEVICES

This device is design 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 control multiple electrical devices by sending suitably formatted SMS message to the microcontroller based control system.  These SMS commands are interpreted by microcontroller system and are validated. If the SMS command received is valid then it takes the necessary action to control the said devices.
This system also continuously monitors the status of devices connected to it. If the status of any critical device changes from ON to OFF or vice versa, then microcontroller based system automatically sends the SMS alerts back to user. After completion of the command implementation this system sends the confirmation messages back to the calling user.
