Normally in our day to day life we lead towards automating things. Using different types of sensors we can easily count any parameters and keep a data log for analysis. Likewise somehow we require automation to operate our home appliances without any physical efforts e.g. to turn on fan with wireless remote. With this inspiration I made this project to automate electrical home appliances with wireless remote. As we know RF based wireless remotes are generally used in toys. Here this system controls output load connected to it consisting RF transmitter and RF receiver pair. As name suggest RF transmitter uses radio frequency of 434 MHz band to communicate with maintaining specific baud rate .This RF module available ready-made in market which makes this circuit reliable to make .
