Rf Remote Control Circuit Diagram

You can also connect relay in place of leds and then you can control ac appliances wirelessly using rf remote.

Rf remote control circuit diagram.

Making a 433 mhz 315 mhz rf remote control with relay flip flop. Rf remote control circuit designed with 434 mhz ask amplitude shift keying transmitter and receiver here ic ht12e act as encoder and ic ht12d act as decoder this circuit is constructed with easy available components. The circuit is using a dpdt relay at the output from which you can connect your home appliances to operate them wirelessly like fan lamp etc. Every rf wireless bell is consist of two parts which are a rf transmitter remote control and a receiver with a music or alarm generator.

This remote gives approximately 150 meter coverage by extending the ariel wire it can be increased up to 200 meters. The control signals from remote switches along with 8 address bits constitute a set of 12 parallel signals. Building a hi end remote control device using very few components today looks pretty plausible. This project has two stages that is 1.

Hope you understood the project and enjoyed building one. You can also purchase a hello readers we frequently add new circuit diagrams so do not forget to come back often. This is a project of an rf remote control relay switch circuit. The encoder ht12e encodes these parallel signals into serial bits.
