Control The Wastage of Electricity Using GSM Controller

This paper proposed a new way to control home or industrial electrical appliances by using missed call based GSM technology. This system is very useful in home and industry automation. The main controlling unit is microcontroller, GSM SIM 900 (for communication purpose) and the relay circuits that is used for switching (ON/OFF) the electrical appliances. In this system communication part is done by using GSM SIM 900, which gives signal to the microcontroller. Controlling system is reach by using ATMEGA 328 P PU Microcontroller, which works on the how many rings received by the controller and accordingly switching operation is done by using relay circuitry. This system works on missed call based approach and gives free of cost communication, which is the best part of this system. This system can also give a feedback as per the user requirement towards the controlling or switching (ON/OFF) the electrical appliances.
