Abstract :
This paper is about controlling the home appliances from anywhere around the world. This also helps for the people who are physically challenged so that they can operate the appliances in the home using mobile phone. Sometimes there may be chance, to forget to switch off the appliances at home and there may the wastage of power. So, the solution for the above problem is DTMF(Dual Tone multiple Frequency) controlled home automation. The DTMF based automation is controlled by the mobile signals. Using a DTMF technique, the DTMF decoder is connected to the relay which is controlled by the mobile phone by making a call to the other mobile phone which is attached to the DTMF decoder. Thus the home appliances are controlled using DTMF decoder output using mobile phone without using microcontroller.
