Rf Remote Control Switch Circuit Diagram

This is a remote controllable light switch that comes with an rf remote.

Rf remote control switch circuit diagram.

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. The circuit has also a good range of upto 20 meters. The whole project contains two parts which is an fm transmitter and a rf receiver. Circuit diagram of infrared remote control switch.

For good results use a good quality fm transmitter with the circuit. 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. Circuit diagram of remote controlled switch output of tsop1738 oscillates at the rate of 38khz which is applied to clock pulse of 4017. This remote gives approximately 150 meter coverage by extending the ariel wire it can be increased up to 200 meters.

In the receiver section there are 3 photodiodes which will detect the infrared signals from the receiver and produce leakage current to the capacitor c1. This is a project of an rf remote control relay switch circuit. This project has two stages that is 1. So we have connected a 1uf capacitor across the output of the tsop so that this 38khz pulse train is counted as one clock pulse to the ic 4017.

A relay switch is used at the output of the circuit which can be connected with the appliances to make them switch on off.
