Rf Remote Control Switch Circuit Diagram

The building s basically a 1 room apartment so this works out great with the remote.

Rf remote control switch circuit diagram.

The only light switch is across the room from my pc and it s a pretty large room. This is a project of an rf remote control relay switch circuit. This current is given to the inverting input of 3130 ic which will get triggered by this current and give amplified output. The whole project contains two parts which is an fm transmitter and a rf receiver.

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. 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 circuit has also a good range of upto 20 meters. 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 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 is a remote controllable light switch that comes with an rf remote. For good results use a good quality fm transmitter with the circuit.
