Rf Remote Control Switch Circuit Diagram

Circuit diagram of remote controlled switch output of tsop1738 oscillates at the rate of 38khz which is applied to clock pulse of 4017.

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 current is given to the inverting input of 3130 ic which will get triggered by this current and give amplified output. Circuit diagram of infrared remote control switch. This project has two stages that is 1.

For good results use a good quality fm transmitter with the circuit. 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. 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. 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.

The circuit has also a good range of upto 20 meters. A relay switch is used at the output of the circuit which can be connected with the appliances to make them switch on off. The whole project contains two parts which is an fm transmitter and a rf receiver. This is a project of an rf remote control relay switch circuit.

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