Simple infrared remote control switch circuit diagram

Using infrared remote control as a switch control is a lot of work, you can find some good designs on the network. However, to realize the remote control switch, a remote controller and a receiver are generally required.

Here you will have the opportunity to make such a device, just do the receiving part, the transmitting part can be remotely controlled using a normal TV remote control, quite simple.

Because the remote control receiver board has code automatic learning function, you can freely select any button in the TV remote control as the control button to realize the switching function.

The learning process of receiving the code is as follows: press the tact switch of the receiving board, the LED is lit, then you can now press any button of the remote control. If the LED of the receiving board is shining, it means that the receiving board has been learned. .

Making such a remote control switch is very simple, even beginners can do it well, because this circuit is too simple, just a dozen components can be completed. Because the use of a microcontroller as a program processing chip, the circuit and its simplicity. The MCU uses the PIC12F629, and the integrated remote control receiver uses the TSOP1738. Of course, if the receiver of this model is not found, an alternative model can be used. The relay can be used with a normal 12V relay.
