I want to send sensors data from arduino to nodemcu using RF ModuleThe arduino is using a transmitter and the nodemcu is using the Receiver
Is there any sources or way to send data from arduino to nodemcu and display it on webserver? I want to get data from sensors of Arduino Board and send it to the Nodemcu by using the RF Module then display the data using the nodemcu web server
Sure there are. The main thing is using a transmitter to send and a receiver to receive. Use controllers, boards that can handle a/the transmitter and a/the receiver.
As You have not specified things, "arduino, an RF module, a receiver" You get no precise reply. There are some 10 different Arduino boards, tons of RF transmitters and receivers....
Do You get it?
Split Your thinking into parts. Use Google for the small parts like "Arduino + RF transmitter", "Arduino + RF receiver", "Arduino + web server".
Because - due to poor design of the forum - that is the first forum in the list. And it is called "troubleshooting" after "installation", which is what almost all of those posting fancy they are doing once they have installed their Arduino.
The real question is - so why would you ever expect anyone not to post in that forum given its obvious title?
NodeMCU has RF built-in. WiFi is just another type of RF. Why not forget the "Arduino", connect the sensors direct to the NodeMCU and use its wi-fi instead?
If your answer is that the Wifi range is not good enough, are you sure that the other type of RF you were planning to use has better range? Many types have a range that is pretty similar to wi-fi. Some only have have range that is better than wi-fi but only if you use higher gain antenna. But if you use higher gain antenna with wi-fi, you would get similar results.
Only a few types of RF transmitters/receivers have a range that is significantly better than wi-fi, such as LoRa.
If you want to try different antenna with wi-fi, you could try a wemos D1 mini Pro. These are similar to NodeMCU (same number of useful pins, but none of the useless pins) and you can connect an antenna of your choice, for example a directional wi-fi antenna. This should give better range than than the built-in antenna.
Not sure that post ("RTFM") is in any way appealing!
They are not particularly interested in "the best out of the forum". That is just some sort of airy-fairy notion. They just want to post their problem.
