The main objective of this DTMF BASED REMOTE CONTROL SYSTEM project is to develop an embedded system which can control remote appliances remotely by using telephone line. In this Embedded System Project we are going to develop an embedded system which will control the remote appliances with the telephone lines. We can control more than 10 electrical Appliances;

In this Final Year Engineering project describes, through the telephones all the electrical system are control by remotely like light switches,air coolers, Washing Machines, Televisions, Small motors and etc……

First of all the telephone lines of data are transmitting through the transmitter by the encoder, it will encode the data without noise, and then the data will be received at the receiver, so that the receiving data is decode as original data of telephone line by the decoder, then the original data is stored in microcontroller and it will control the all the electrical system.

SOFTWARE: Embedded ‘C’ Language

TOOLS: Keil & flash magic Tool.

TARGET DEVICE: LPC2148  (ARM7) Microcontroller

APPLICATIONS: All Important Electrical appliances.

ADVANTAGES: Possible to control the Embedded device from the remote locations
