The project RF based home automation system is developed to automate the use of conventional lighting mechanism (wall switches) in house by using RF controlled remote. The project requires a RF remote that is interfaced to microcontroller (of 8051 family) on transmitter side which sends ON/OFF signals to the receiver. Receivers are connected with loads that can be turned ON/OFF by operating remote switches on transmitter wirelessly. Here the loads are interfaced to microcontroller by utilizing opto-isolators and triacs. Thus the system serves a convenient way of lighting up the house without any physical movements.
