RF Wireless Controlled Home Automation (On/Off 4 Lights/Fans)

On/Off 4 Lights/Fans control through RF communication is a very interesting application and is widely used in robotics, electronics toys, automation systems etc. This topic covers the way On/Off 4 Lights/Fans can be driven by using the controls from a distant place. The controls are transferred from one end to another by employing an RF module.

The remote control application of RF has been extended to operate a motor driver which in turn controls the direction of motors

This circuit uses RF module to control On/Off 4 Lights/Fans through a relay board. Transmission is enabled by giving a low bit to pin14 (TE, active low) of encoder HT12E. The data signals of encoder HT12E work on positive logic. Therefore a particular signal is sent by giving a high bit to the corresponding data pin of encoder.

The parallel signals generated at transmission end are first encoded (into serial format) by HT12E and then transferred through RF transmitter (434 MHz) at a baud rate of around 1-10 kbps. The same signals are acquired by RF receiver after which it is decoded by HT12D.
