Abstract

Now a day’s mobile has become an area of our standard of living. Due to low value of mobile phones, that’s why we are widely used for home automation. In this paper a remotely operated mobile controlled home appliances system is projected. It is a DTMF (Dual-Tone Multiple-Frequency) based system consist of two mobile phones, DTMF decoder and one microcontroller. One mobile is employed as remote which can find a way distance from home and another mobile is found at the house that act as a receiver. The DTMF signals send via the remote mobile as DTMF tone. This DTMF tone is received by the mobile phone installed at home. The received DTMF tone is then decoded by DTMF decoder IC. The output logic signals of the decoder used as an input to the microcontroller. The microcontroller is antecedently programmed to manage home appliances in line with output of the DTMF decoder.
