RF based Home Automation system using 8051 microcontroller

In today’s highly developing world most of  peoples wantstheir homes areautomated as per increased level of affordability,simplicity  and comfort through the integration of home appliances with smart phone and tablet connectivity.Home Automation system that controls various home appliances such as a fan, bulb, AC, TVetc. with RF remote controller..

So here we introduce Home automation system which is developed to automate the use of conventional lighting mechanism (wall switches)in house by using RF controlled remote that sends ON/OFF signals to microcontroller.

Block diagram:-

The system is mainly based on RF modules is the combination of RF transmitter and RF receiver which used as remote to controlled the system. So user can simply give the commands through the RF remote which are received by RF transmitter then it will sends to the microcontroller and then microcontroller will handle the particular load.

The micro controller is programmed in a way that whenever the command is given through the RF remote for driving the appliances on and off, it communicates with the relay circuit. Suppose if u want ON the load 1 then you simply press the button 1 on RF remote then this signal will received by transmitter and send to microcontroller then it will ON the load 1 and massage will be displaying on LCD.
