Hello there How are you? I am an special electronic engineer and have done electrical and PCB design projects for you. You want to control relay for transmitter and receiver. I think this project is very suitable for me. I can easily implement the circuit that you attached. If you are interested in my suggestion, we can discuss in detail via chat. Thank you Alexander

Instead of using that approach - which is impacted by noise and quality is not good - it is much better to use 315MHz or 443MHz RF. My proposal is: - Transmitter send a magic code every 5 seconds via RF when it is connected to power supply. - Receiver, once received the code, will turn on the relay. After 5s if no code, it will shut off the relay. A special encoding is used so that noise or any interference from other rf source does not impact to the circuit. The range between the transmitter and the receiver is about 30m to 100m. Let me know if you have any question.
