Abstract

Dual Tone Multi Frequency (DTMF) technique for controlling the domestic and industrial appliances is being presented in this paper. A simple mobile phone which works on DTMF tone, used to control the domestic as well as industrial electrical appliances which with the control system which we have designed here for experimental study. In recent state of affairs, domestic, military and industrial applications use this technique because it can be operated from remote location. Radio frequency (RF) is also used for wireless communication but DTMF is an alternate for RF. Mobile phone is used to send the DTMF code from remote location to the control system. The blocks of system are mobile phone, Microcontroller (AT89S52), DTMF Decoder (MT8870D), Relays and power supply. This paper shows the working areas where the system is applicable and how it has advantages over RF.
