To control processes of his / her choosing, the human mind also needs knowledge of interest. Most methods of remote control systems have been developed in the age of technologically advanced electronic systems, these methods have the problems including the need for special hardware and software to operate the machine. In recent years, Automation Systems based on intelligent networks have been built in manufacturing, commercial and residential sectors. The concept of remotely controlling the devices can be introduced using various wireless technologies such as ZigBee, GSM / GPRS, Bluetooth, but these technologies require software creation, dedicated computers, and network setup schemes. Then implementation is time-consuming and they also make the program expensive. This paper introduces a more responsible, cost-effective Mobile Operated Automated System based on DTMF (Dual Tone Multiple Frequency) theory. It uses Mobile as the receiver end control system and existing Telephone Network infrastructure. The noise in the method is also reduced using Goertzel DFT estimation, and its full analysis is provided.
