Rf Remote Control Switch Circuit Diagram

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. 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. The whole project contains two parts which is an fm transmitter and a rf receiver.

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.

Rf remote control switch circuit diagram.

This remote gives approximately 150 meter coverage by extending the ariel wire it can be increased up to 200 meters. This project has two stages that is 1. This current is given to the inverting input of 3130 ic which will get triggered by this current and give amplified output. The circuit has also a good range of upto 20 meters.

The building s basically a 1 room apartment so this works out great with the remote. Circuit diagram of remote controlled switch output of tsop1738 oscillates at the rate of 38khz which is applied to clock pulse of 4017. For good results use a good quality fm transmitter with the circuit. This is a remote controllable light switch that comes with an rf remote.

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. Circuit diagram of infrared remote control switch. A relay switch is used at the output of the circuit which can be connected with the appliances to make them switch on off. This is a project of an rf remote control relay switch circuit.

The only light switch is across the room from my pc and it s a pretty large room.
